Response of black gram (Vignamungo L. Hepper) to spacing and fertilizer doses under rainfed conditions

Abstract

A field experiment was conducted during the kharif season of 2012 to study the response of black gram [Vigna mungo (L.) Hepper] to different spacing and fertilizer doses under rainfed conditions. Maintaining a wider spacing of 30×10 cm (S 2 ) was found to increase uptake of nutrients P and K by the crop resulting in significantly higher number of leaves, branches and pods per plant respectively, thereby registering the highest grain and stover yields of 730 kg/ha and 1382 kg/ha respectively. Among the fertilizer dose, F 2 (N 10 P 40 K 20 + FYM@ 5 t/ha) was found to increase the availability of NPK by the crop resulting in significantly superior growth attributes viz., plant height, number of leaves and branches/plant and leaf area index (LAI) ultimately recording maximum number of pods/plant, test weight and grain yield of 725 kg/ha. Whereas, the fertilizer dose F 3 (N 20 P 50 K 30 ) was found to record the highest stover yield of 1362 kg/ha.

Yield, nutrient uptake and post-harvest soil available Nutrient status of dhaincha as influenced by varied times of sowing and spacings

“…Maintenance of higher plant population at 30 cm x 20 cm spacing resulted in higher seed and stalk yield. These findings are in support of Kavin et al (2018) [2] , Tungoe et al (2018) [13] and Shinde et al (2021) [10] .…”

Effect of Foliar Nutrition and Crop Geometry on Cultivars of Blackgram in Shiwalik Foothills of Jammu

“…Higher biomass production especially root proliferation trait of the cultivar might have contributed towards higher nutrient uptake. Similar findings were observed by Tungoe et al (2018). Among different crop geometry treatments closer 30 × 10 cm enhanced the uptake of N, K and molybdenum compared to wider spacing of 45×10cm (Table 4).…”

Improved Pulse Production Technology - A Strategic Tool for Doubling Farmer’s Income: A Review

“…Too low and high plant population adversely affects the crop yields (Melak Agajie, 2018). Plants grown at closer spacing favours self thinning of branches and reported taller plants, while at wider spacing all the growth and yield components per plant observed to be superior due to better competitive advantage of crop favouring better nutrient absorption (Tungoe et al 2018). However, black gram grown under clay loam soil observed to record significantly higher yield with 30×10 cm spacing over 45×10 cm (Murade et al 2014) due to incompetent compensation of yield by wider spacing over more number of plants per unit area, comparatively.…”
