Abstract

The present study aimed to evaluate the effect of spacing and phosphorus levels on blackgram (var. “TYPE-9”) during Kharif 2020 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P) spacing and phosphorus levels seems necessary factors for achieving the higher yield of blackgram. The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.7), low high carbon (0.44%), medium available N (171.48 kg/ha), low available P (27.0kg/ha) and high available K (291.2 kg/ha). The treatment consisted of spacing viz., 20 × 10 cm2, 30 × 10 cm2, 40 × 10 cm2 and nutrient phosphorus application 20 kg/ha, 30 kg/ha and 40 kg/ha. The experiment was laid out in Randomized Block Design (RBD) with nine treatments which are replicated thrice. The results showed that higher plant height (45.93 cm) was recorded significantly higher with spacing 20 × 10 cm2 + 40 kg/ha P2O5 of phosphorus. Whereas, number of branches per plant (6.67), number of nodules per

Conclusion

Based on the findings of the investigation it may be concluded that for obtaining optimum seed yield performance of blackgram under rainfed conditions, maintaining a wider spacing of 30 × 10 cm2 along with 40 kg/ha phosphorus is the best management practice to increase the availability and utilization of nutrients by the crop. Whereas, optimum growth was observed with a wider spacing of 40 × 10 cm2 along with 40 kg/ha phosphorus.
