Blackgram is an important and widely adopted pulse in India. Nevertheless, it´s productivity is low and is increasingly affected by climate change effects. Hence, appropriate adaption strategies are required to mitigate the negative trend.

The overall objective was to study the effect of different sowing methods and nutrient managements on two indigenous blackgram cultivars in regards to growth, yield, economy and quality.

The study was conducted in 2012 during Kharif season (July-October) at farmer’s fields in 10 villages of Sagar district. The soils were divided into vertisol and alfisol clusters and a random block design consisting of three factors was applied: indigenous cultivars (Khajua, Chikna), inorganic nutrient sources (DAP[1], INM[2]) and sowing methods (broadcasting, line sowing). The crops were measured for growth parameters, yield attributes, economic analysis and quality aspects.

Cultivar Chikna showed higher records for some pre- and most post-harvest parameters compared to Khajua. For example, it revealed higher values compared to Khajua for no. of leaves plant-1 (48.80; 43.72, resp.), seed yield (1389.00 kg ha-1; 1113.50 kg ha-1, resp.) and harvest index (33.37%; 26.29%, resp.). Broadcasting achieved higher records compared to line sowing for no. of pods plant-1 (29.95; 27.32, resp.), seed yield (1389 kg ha-1; 1378 kg ha-1, resp.) and harvest index (30.63%; 27.41%, resp.). Regarding nutrient management, INM2 was superior to DAP1, for most of the tested parameters including growth factors, e.g. no. of leaves plant-1 (50.82; 48.80, resp.), yield attributes e.g. seed yield (1557 kg ha-1; 1389 kg ha-1, resp.), protein content (24.70%; 24.00%, resp.) and economic factors such as benefit to cost ration (1.74; 1.70, resp.).

Cultviar chikna, broadcast sowing and integrated nutrient management were found to be the best factors for obtaining highest values for most of the measured parameters of blackgram under rain fed farming conditions. It is recommended, however, to repeat the experiment in several seasons and to conduct it also in other areas.
