In this paper, the investigation is strived to examine the growth trend of major pulses in India. The study is conducted on Bengal gram, Black gram, Pegionpea, Chickpea and Green gram for the 1990- 2020 periods. The total duration of 30 years is divided into three decades to know the in-depth decadal growth of the area, production, and productivity. For the above period, the average compound growth rate (CGR) in major states for Bengalgram as 2.82, 1.34, and 3.5, for Black gram -0.69, 0.53, and 0.215, for Pegionpea 0.65, 1.29, and 0.61, for Chickpea 1.27, 0.96, and 0.74, and for Green gram -0.71, 0.55, and 0.116 is observed in the area, production, and productivity. Decadal growth also approximately reflected similar trend for all the major pulses. Low productivity and low net return are minimizing the profit in this highly remunerative crop.
Pink anemonefish (Amphiprion perideraion) has commercial value as a popular aquarium fish and due to its collection from the wild there are concerns for the conservation of the species. Six polymorphic microsatellites were used to reveal population genetic structure of pink anemonefish from three locations (Quang Nam, Khanh Hoa – Ninh Thuan and Phu Quoc) in Vietnam. Analyses showed evidence for high levels of gene flow among populations sampled from the South China Sea (FST = 0.008, P > 0.05). Genetic homogeneity of A. perideraion in this region is likely due to the oceanographic-driven interaction of pelagic larvae in central waters off Vietnam. In contrast, strong genetic structure was evident among the South China Sea and Gulf of Thailand populations (FST = 0.131 – 0.146, P < 0.01). This high genetic differentiation between the South China Sea and Gulf of Thailand populations suggests that the sustainable management of this species in Vietnam needs to be enacted according to indigenous need as a two separate stocks.
A field experiment was conducted for two years (rabi 2016 and rabi 2017) at SKUAST-Jammu to study the effect of differential substitution nutrients through organics on yield, nutrient uptake and profitability of knol khol (Brassica oleracea var gonylodes L.) in subtropical region of J&K. Experiment was conducted in randomized block design with sixteen treatments. The results of the study revealed that significant effect of differential substitution nutrients through organics were observed on growth parameters viz., plant height, number of leaves plant and dry matter accumulation (g/plant); yield and nutrient uptake at harvest in knol khol during both the years. Significantly highest plant height (33.14cm and 36.44cm), number of leaves/plant (15 and16.20), dry matter accumulation (28.38 g/plant and 32.65g/plant), knol khol yield (712.35q/ha and 734.79q/ha), net returns (Rs 309281 /ha and Rs 211905 /ha) were recorded with recommended dose of fertilizer during both the years where as lowest value of all these parameters were recorded with 100 % N through FYM. Significant difference between treatments was also recorded for nitrogen uptake and potassium uptake during both the years.
Alternaria blight incurring loss both at pre and post-harvest stages in tomato caused by Alternaria alternata become an important constraint for tomato producers in Rajasthan. The severity of this disease generating significant economic losses in crops has been increasing daily for the last few years in Rajasthan due to environmental changes. Field experiments were carried out to examine the development of Alternaria blight in tomato relevant to weather conditions during zaid 2017 and 2018 at SKNAU Jobner (Jaipur). Results showed that maximum temperature (r= 0.9032 Unit in 2017 and 0.8893 in 2018), minimum temperature (r=-0.8590 in 2017 and 0.8512 in 2018), relative humidity maximum (r=-0.6184 in 2017 and -0.8562 in 2017), relative humidity minimum (r=- 0.6840 in 2017 and -0.5477 in 2018) and rainfall (r=-0.6161 in 2017) had shown significant negative correlation with disease severity index (DSI). The mean value of the minimum and maximum temperature during this period ranged from 15.630C to 35.740C and 15.750C to 36.240C during 2017 and 2018, respectively. Development of disease observed in favourable mean relative humidity ranging from 25.33 to 63.00 and 16.66 to 58.00 per cent. The coefficient of multiple determinations (R2) was 74.50 and 92.40 per cent during 2017 and 2018, respectively.
A field trial was conducted during Kharif season of 2017 at the Agronomy Research Farm, Faculty of Agriculture of Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir, Wadura to evaluate the resource-use-efficiency of intercropping of sweet corn (Zea mays L. saccharata Sturt) with Rajmash (Vigna vulgaris L.) and soybean (Glycine max L. Merril). The intercrops were grown in additive series with sweet corn as regular rows of 1:1 and paired rows of 2:1 and 2:2. The experiment was laid out in randomized block design having three replications. Among intercropping, sweet corn grown in association with soybean in 1:1 row ratio recorded significantly higher values of growth parameters such as LAI and percent PAR intercepted. The resource-use efficiency in terms of radiation use efficiency and irrigation water-use efficiency were significantly highest with sweet corn + soybean (1:1) intercropping followed by sweet corn + bean (1:1). From the present study, it was concluded that intercropping of sweet corn with soybean in regular rows of 1:1 ratio could achieve higher productivity and profitability among different intercropping systems.
