Subject: Marching towards self-sufficiency in chickpea
Keywords: Chickpea, improved varieties, production technologies, self-sufficiency
Abstract: Chickpea is a major pulse crop of India accounting for more than 40% of the total pulses area and production. From a mere 3.86 million tonnes (mt) during 2000-01, chickpea production rose steadily to an all-time high of 11.23 mt during 2017–18. The central and southern states such as Madhya Pradesh, Maharashtra, Rajasthan, Andhra Pradesh, Karnataka, Gujarat, Chhattisgarh and Jharkhand have benefited most
from chickpea revolution in the country, with remarkable increase in both area and production. This has been achieved through development of suitable technologies like high-yielding varieties along with matching production and protection technologies,
quality seed producing units, etc. To attain self-sufficiency by 2050, the total pulse production in the country needs to reach 39 mt. This includes chickpea requirement of about 16–17.5 mt by 2050 from an
area of about 10.5 m ha with average productivity of 15–17 q/ha. The potential yield observed in AICRP (Chickpea) trials has increased from 10 to 17.50 q/ha
during the past 20 years (CAGR = 1.51%). At this rate, the increased chickpea requirement can be easily achieved by 2050, provided there is proper policy
backstopping. Here we review chickpea research in India during the last five decades and future research priorities to tackle newer challenges.

Abstract: In continuation of the comprehensive review on clinical islet transplantation by
Saravanan et al that focuses on the
global scenario, it is appropriate to consider this important issue in the Indian context. The advantages and safety of islet transplantation in selected patients
with type-1 diabetes mellitus (T1DM),
experiencing life-threatening episodes of
severe hypoglycaemia and in patients
undergoing total/partial pancreatic resections, have been well demonstrated in the western as well as in certain Asian countries. Such transplantation is recognized by their national health systems and is reimbursable by their insurance systems.

Keywords: Carbon stock assessment,climate change mitigation, North East India, Nagaland
Abstract: Forests are the most important terrestrial
ecosystems on earth, as they have rich
biodiversity, provide ecosystems services
and have the capacity to offset climate
change impact through carbon sequestration. North East (NE) India, one of the 35 biodiversity spots of the world,
comprises 8 states and has an area of
171,964 sq. km (65% of the geographical
area) under forests . Another major land
use in NE India is agricultural land. Although 86% of this area is under ‘shifting or jhum’ cultivation, it is the main
source of livelihood for the local people.
In NE India, clearing of forest lands,
burning of vegetation and conversion into jhum fields is a common practice. This
practice not only increases soil fertility
for 1–2 years, but also aggravates issues
of soil erosion and carbon loss after the
cultivation phase.

Subject: Chenopodium species: from weeds to a healthy food grain ‘quinoa’
Keywords: Chenopodium species, healthy food grain, ‘quinoa
Abstract: Genus Chenopodium has about 250 species, which mostly grow as weeds throughout the world. In India, the
most common species is Chenopodium album L., which grows as a weed in wheat fields in the north. Its foliage is used as a green vegetable, while the seed is used in the hilly regions for making gruel and mild
alcoholic beverages. However, people of Andes, South America have domesticated and developed Chenopodium quinoa (popularly known as quinoa) as an excellent food-grain crop since the past several millennia. Quinoa received global attention in the wake of human intolerance to gluten in wheat resulting in celiac disease, and its demand has largely increased. The United Nations General Assembly declared 2013 as the International Year of Quinoa. The leading country in the world producing quinoa is Peru, followed by Bolivia. However, considering the demand and high market prices, a number of countries, including India have started growing quinoa. However, farmers in India are facing problem in marketing the crop, because there is no local consumption and exporting a farm product is problematic. India has a variety of food grains,
including pearl millet, sorghum and several minor millets to tackle gluten intolerance and celiac disease.

Subject: Diminishing forest area in the Western Himalaya: apprehensions for the loss of vital biodiversity
Keywords: Diminishing forest area, Western Himalaya, vital biodiversity
Abstract: The Western Himalayan Region (WHR)
is one of the best studied ecoregions of
India known for its rich biodiversity. It
supports over 4500 species of angiosperms, over 20 species of gymnosperms, 350 species of pteridophytes, 1063 species of birds and nearly 33% of Indian mammals.
. Threats to biodiversity are high in the region, as much of the local populace is dependent on these forests for its day-to-day needs. In recent years, the stresses on forests of the WHR have become more intense due to unsustainable developmental activities as well as an increased frequency of natural disasters. Beside the tangible benefits such
as biomass products that are extracted by
the local populace, these forests provide
numerous critical ecosystem services
such as supporting biodiversity, providing habitat for wildlife and regulation of
various hydro-geological cycles.

Abstract: Streams contain surface and groundwater
fluxes, responding to geological, geomorphological, hydrological and biotic
control in a region, which form a decisive part of the earth’s water circulatory
system. Surface water flowing within the
bed and banks of streams transports
sediments, nutrients and other materials
into streams, rivers and lakes, and onto
the ocean. Streams perform vital ecosystem functions such as providing habitat (for aquatic and terrestrial biota), mitigating instances of floods, groundwater
recharge, provision of drinking water,
bioremediation, etc.

Abstract: At present there are different models of coconut climbing devices available in the market. The safety and efficiency aspects of coconut climbing devices are not being studied for women. Therefore, a study was
undertaken to evaluate the existing models of five coconut climbing devices, sit and climb type (TNAU model), standing type (Chemberi model), KAU coconut palm climber (developed at KCAET, Tavanur,
KAU), Kerasureksha (model developed at ARS, Mannuthy, KAU) and CPCRI model coconut climbing device on ergonomic basis for women operators. Minimum heart rate and energy expenditure was observed
for KAU coconut palm climber than other models. The subjects felt less safety in operating TNAU model and standing type (Chemberi model). Sit and climb type (TNAU model) was found difficult to operate compared to other devices. On basis of these results, it was found that KAU coconut palm climber was more suitable and ergonomically comfortable for the women operators.

Subject: Effects of small rainfall events on Haloxylon ammodendron seedling establishment in Northwest China
Keywords: Arid regions, Haloxylon ammodendron, seedling establishment, small rainfall events.
Abstract: Small rainfall events (5 mm) account for a large proportion of rainfall amount and may play an important role in triggering plant regeneration in arid ecosystems. However, their potential ecological importance in seedling establishment of desert shrub
has been previously ignored. We conducted two parallel pot experiments to examine the effects of amount and interval of small rainfall events on seedling emergence, growth and survival of the dominant shrub
species Haloxylon ammodendron in sand dunes of Northwest China. The results showed that: (1) decrease in rainfall amounts did not significantly lower seedling emergence, growth and survival in comparison to control, while the large increase (+20%) in rainfall amount resulted in significant increase in seedling emergence, growth and survival for both continuous and intermittent small rainfall events; (2) continuous small rainfall events were more effective than intermittent ones for triggering seedling emergence,
growth and survival; (3) small rainfall events may impact the seedling establishment of H. ammodendron only in wet years. Our results provide insights into the effects of small rainfall events on seedling establishment processes and highlight the inherent complexity in predicting how seedling establishment of shrub species in desert ecosystems will respond to future fluctuations in small rainfall events.

Abstract: This study was carried out to evaluate the efficacy of agriculturally beneficial fungi for potash solubilization and to develop myco-potash cultures for use in crop growth. In all six fungal cultures were utilized in the study, viz. Paecilomyces lilacinus, Tricoderma harzianum, Aspergillus wentii, Emericella nidulans, Verticillium lecanii and Tricoderma viride. Among them, A. wentii and T. viride were found to produce 3.3 and 3.65 mm solubilization index around the colony after 7 days of incubation (DAI) on Aleksandrov medium supplemented with mica as potash source. Whereas for agar medium supplemented with feldspar, maximum solubilization index was 2.5 mm (A. wentii),
2.55 mm (T. viride), 2.48 mm (V. lecanii) and 2.58 mm (P. lilacinus) 7 DAI. To reveal the mechanism of potash solubilization, A. wentii, T. viride, T. harzianum and V. lecanii were chosen for organic acid profiling
using HPCL. A. wentii produced the highest amount of total organic acid (1847.775 μg/ml).

Subject: Carbon sequestration potential of Hardwickia binata Roxb. based agroforestry in hot semi-arid environment of India: an assessment of tree density impact
Keywords: Agroforestry, allometric equation, arid and semiarid regions, silvipasture, C-sequestration, tree density
Abstract: Agroforestry is one of the most promising options for climate change mitigation through carbon sequestration. However, carbon sequestered in agroforestry system depends on various factors like type of tree
species, tree density, system age, soil and climate. One of the most important factors for enhancing carbon sequestration per unit land is tree density. Hardwickia binata Roxb. has been reported as suitable agroforestry tree species with multiple benefits in arid and semi-arid region, however, the role and impact of tree density in carbon sequestration is poorly reported.
This study estimated impact of tree density (D1 = 333 tree ha–1 and D2 = 666 tree ha–1) on carbon sequestration potential of 30-year-old H. binata Roxb. + Cenchrus setigerus silvipasture system in hot semiarid
region of Rajasthan. The carbon sequestered in tree biomass was estimated by reported allometric equations, whereas in soil it was determined by Walkley and Black method. Results showed significant impact of tree density on carbon sequestration per unit tree and per hectare land. The average biomass carbon sequestered by a tree was significantly more (44.5%) in low density (D1) compared to high density (D2) system. However, total biomass carbon sequestered per hectare land was significantly more (40.8%) in high
density system (31.6 ± 12.6 Mg C ha–1). Carbon sequestered in soil organic matter was higher in both D1 and D2 systems compared to control (sole Cenchrus
setigerus field). It ranged from 19.93 ± 0.31 Mg C ha–1 in control to 22.94 ± 0.65 Mg C ha–1 and 23.25 ± 0.78 Mg C ha–1 in D1 and D2 respectively. The total carbon sequestered (below and above ground tree
biomass and soil organic carbon) was in the order D2 > D1 > control.

Subject: Coal–rock interface recognition based on permutation entropy of LMD and supervised Kohonen neural network
Keywords: Coal–rock recognition, local mean decomposition, permutation entropy, supervised Kohonen neural network, sound signal.
Abstract: Owing to the difficulty in coal–rock interface recognition during the process of coal mining, the shearer is damaged at a high frequency. To avoid this problem,
a method is proposed for coal–rock interface recognition based on permutation entropy calculated using the local mean decomposition (LMD) method and supervised Kohonen neural network (SKNN) by performing sound signal analysis. The complex and nonstationary sound signal is adaptively decomposed by LMD. Given that the decomposed product function (PF) components contain the main information of the features, permutation entropy (PE) is used to reflect the complexity and irregularity in each PF component and is defined as the input of the SKNN model. Finally, the optimal SKNN model is obtained by training the samples. The experimental results show that the comprehensive recognition rate of a coal–rock interface is up to 89%. A coal–rock interface can be recognized effectively by sound signal analysis.

Subject: Impact of ultraviolet-B radiation on growth and biochemical composition of Botryococcus braunii Kutz.
Keywords: Botryococcus braunii, chlorophyll a, oxygen evolution, ultraviolet-B radiation
Abstract: The present study examines the impact of ultraviolet (UV-B) radiation stress on commercially significant microalga for biofuel application. Experimental alga
Botryococcus braunii was treated under different doses of artificially enhanced UV-B radiation. The organism was treated under high dose rates of 1 and 5 Wm–2 with altered time durations of 15, 30, 45 and 60 min. It showed large variations in the growth characteristics analysed. The rate of whole-cell photosynthetic oxygen evolution showed steep drop in high dose compared to low dose-treated cultures. As a result, level of photosynthetic pigment chlorophyll a content decreased drastically while carotenoid level invariably increased.
Consequently, the level of primary metabolites such as total carbohydrate, protein and lipid was drastically reduced under high dose while marginal decrement
was observed at lowest dose of UV-B radiation. Overall, the impact of UV-B radiation on B. braunii led to a drop in protective mechanisms with associated
decline in growth and cellular imbalance at high intensity studied.

Subject: Biophysical performance of different multipurpose trees species in Jharkhand, India
Keywords: Agroforestry, biophysical performance, CO2FIX model, multipurpose trees species, tree biomass.
Abstract: An experiment was conducted to evaluate the performance and characterize plant growth behaviour, light profile and soil fertility status of seventeen different
trees (12 years old). The study indicated higher biomass production potential of Gmelina arborea, Dalbergia sissoo and Leucaena leucocephala. Higher
photosynthetically active radiation value below tree canopy indicates compatibility of trees with a majority of agricultural crops. In the present study, a significant increase in pH and decrease in EC of trees were
observed. The significant reduction in nutrients in different trees indicated a need for replenishment of nutrients in soil for maintaining soil fertility in agroforestry systems on long-term basis.

Subject: Regression equations for estimating tree volume and biomass of important timber species in Meghalaya, India
Keywords: Biomass, regression equations, tree volume, timber species.
Abstract: Linear regression models were developed for four ecologically and economically important tree species of Meghalaya, India, viz. Betula alnoides, Duabanga grandiflora, Magnolia champaca and Toona ciliata. In
the present study a non-destructive approach has been used for measurement of required variables, i.e., diameter at breast height (DBH), basal diameter, tree
height, end-diameters and length of frustum. Comparison of various models of relationship on the basis of adj. R2
values showed that the value for linear function (V = f (d2 h)) was more than 0.90 for all the four tree species, except lowest diameter class of T. ciliata (10–30 cm diameter class). Hence this linear regression equation was selected for development of diameter class-wise volume equations. Volume of the stem was taken as the dependent variable, while DBH and
tree height were used as independent variables, transformed in the form of d2
h to develop regression equation. Similarly, linear regression equations for each tree species were also developed using linear function [(V = f (d2 ))], considering tree volume as an dependent variable and DBH as an independent variable, transformed in the form of V = d2 . The present study
is among a few attempts to develop regression models without the felling of trees since 1977 and an initial attempt using advanced measurement equipment in
North East (NE) India, under the current regime of ban on tree felling. The regression equations developed in this study can be used for estimation of
timber yield and carbon content of the selected tree species found in the Meghalaya forests.
