Irrigation levels

Field experiments were conducted for two consecutive years during summer season of 2015 and 2016 to study the effect of different irrigation regimes (I1- 0.8 IW: CPE, I2- 0.6 IW: CPE and I3- 0.4 IW: CPE) and row spacing (S1- 45 cm and S2- 30 cm) on varieties (V1- Meha and V2- GM 4) of mungbean crop. Results found that higher grain yield (1380 kg ha-1 and 1437 kg ha-1 ) was found in I1 followed by I2 and I3 in both the years of experiments. Pooled results revealed increase in grain yield in irrigation level I1 was to the tune of 18.5 and 83.

The field experiment was conducted on watermelon (Citrullus lanatus Thunb) cv. Kiran in summer season for two consecutive years viz., 2015 and 2016 at Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani. The objective of this study was to determine the effect of different mulches (black plastic mulch, transparent plastic mulch, soybean strawmulch and control)on root zone temperature, growth and fruit yield characters of watermelon under different irrigation levels. Among the mulches soil temperature in transparent and black plastic mulch applications were higher (2.5 – 5.3 0C and 2.2 – 3.
