Blackgram

Blackgram or urad gram is a short term crop i.e 90days usually grown as winter crop sown during Karthigai pattam. In Dec'2022, this crop was raised.

Blackgram has 15432.358 grains per kg.

With 4’ spacing, there are roughly 11000 running feet. With a spacing of 2 ft, there are 5500 wet areas.

Modifying the recommended spacing of 10cm*30cm, we can have 5 in star pattern + 4 with casuarina in center. Thus we can have maximum of 9 in star pattern or minimum of 5 in straight line.

Plant rate can thus be 2750*(3+2) = 24,750 per acre. With backup seeds, we need 49,500 seeds per acre. With 15432.358 grains per kg, we need 3.24 kg per acre.

Influence of fertigation on blackgram

Experimental design adopted was RCBD with three replications and thirteen treatments consisting of different combinations of water soluble fertilizers viz.,19:19:19 (N: P: K) and Mono potassium phosphate (0:52:34) sprayed at 30 and 45 days after sowing with or without liquid plant growth promoting rhizomicrobial consortia application along with the package of practice.

The Results revealed that, foliar application of 19:19:19 (N: P: K) and Mono potassium phosphate (0:52:34) @ 1 per cent each at 30 and 45 days after sowing + PGPR along with a package of practice recorded significantly higher plant height (67.16 cm), number of branches plant-1 (10.63), number of leaves plant-1 (16.95), leaf area (5.57 dm 2 plant-1), total dry matter production (15.84 g plant-1), number of pods plant-1 (25.20), pod length (7.92 cm), number of seeds pod-1 (6.53), seed yield (1167.62 kg ha-1) and haulm yield (2019.37 kg ha-1) over package of practice.
