“…The increase in these yield attributes at wider spacing was due to better crop growth, more space available for plants, lesser competition for moisture and nutrients between plants. This result is corroborating with the findings of Chaniyara et al (2002) and Rajeshkumar et al (2017). Growing the crop at 30 × 10 cm spacing resulted in 28 and 24% higher pod yield over the closer spacing of 25×10 cm and 20×10 cm, respectively.…”

An experiment was conducted during kharif season of 2016 and 2017 at College of Agriculture, Gwalior. To optimise plant population and fertility levels an experiment was laid out in split plot design, replicated thrice in fixed plots and the test variety of the crop groundnut (Mallika) was used. The plant geometry of 30 × 10 cm, 25 × 10 cm and 20 × 10 cm was adopted with three fertility levels as 75, 100 and 125% recommended dose of fertilizers. The yield and economics were increased by optimization of plant geometry and nutrient management under kharif groundnut. Sowing of crop at 30×10 cm spacing resulted in 7.3 and 4.3 % higher pod yield over 25×10 cm and 20×10 cm spacing, respectively and 3.0 % higher haulm yield over 25×10 cm. Similarly, application of 125% RDF resulted in 3.0 and 9.3 % higher pod yield over 100% RDF and 75% RDF, respectively but application of 100% RDF resulted in 18.6% higher haulm yield over 75% RDF and was at par with 125 % RDF application. The highest gross, net returns and B:C ratio was obtained at the spacing of 30×10 cm with 125% RDF.

“…This resulted in efficient nutrient translocation from source to sink. These results fall similar to the findings of Kunjammal and Sukumar [9], Kiruthika et al [10] and Rajeshkumar et al [11], who could find improved yield attributes due to the application of crop boosters [12][13][14].…”

A study was carried out in foxtail millet regarding the effect of various foliar treatments in combination with recommended dose of fertilizer on the growth and yield of the crop at Tamil Nadu Agricultural University, Coimbatore during the summer of 2021. Eight treatments in combinations with 100% of the Recommended Dose of Fertilizer (RDF) were arranged in a randomized block design with three replications. Foliar treatments applied were viz., 3% panchagavya along with recommended dose of fertilizer (T1), 3% vermiwash along with recommended dose of fertilizer (T2), 3% TNAU maize maxim along with recommended dose of fertilizer (T3), 1% urea along with recommended dose of fertilizer (T4), 1% KCl along with recommended dose of fertilizer (T5), 0.5% zinc sulphate along with recommended dose of fertilizer (T6), 0.5% iron sulphate along with recommended dose of fertilizer (T7) and recommended dose of fertilizers alone (T8). Each treatment was applied at the active vegetative growth stage and panicle initiation stage of the crop. The application of full dose of fertilizer along with a foliar spray of 3% maize maxim resulted in higher plant height (132.38 cm), number of tillers (2.37), leaf area index (1.37), dry matter production (5937.74 kg/ha), productive tillers per plant (1.95), panicle length (23.59 cm), panicle weight (15.29 g), grain yield (2130.20 kg/ha) and straw yield (4108.14 kg/ha). The plots treated with recommended fertilizer alone had the lowest level of all parameters. Treatments with foliar spray of 3% panchagavya and 3% vermiwash were statistically on par with maize maxim application. The result of the experiment implies that foliar treatment of 3% TNAU maize maxim had a significant effect on growth and yield attributes of foxtail millet.

“…This may be attributed for the increased plant height and reduced total number of productive branches in high density planting. These results are in agreement with Joshi et al(2019), Rajeshkumar et al (2017), Murad et al (2014, Kumar and Badiyala (2005).…”

Background: Redgram is an important food legume which is largely cultivated under rainfed condition. In India rainfed agriculture contributes 80% of the total pulses production and the projected requirement will be 39 million tons by 2050 which necessitates an annual growth rate of 2.2%. The productivity has to be increased from the present level of 834 kg ha-1 to 1200 kg ha-1. With adoption of suitable agronomic management strategies the productivity could be increased to meet our demand and achieve self sufficiency in production. Hence the current study was carried out to increase the productivity of redgram under rainfed condition.Methods: Field experiment was conducted in farmer’s field in Madurai district, Tamil Nadu during North East Monsoon season of 2019 to study the effect of improved agronomic manipulations on growth and yield of redgram under rainfed ecosystem. Agronomic management approaches viz., nipping of primary branches at 45 and 60 days after receipt of soaking rain, high density planting at 30 cm × 30 cm in addition to recommended spacing of 60 cm × 30 cm and foliar application of 1% PPFM spray were compared with farmer’s practice in the redgram variety Co (RG) 7. Pre monsoon sowing has been taken up and the rainfall received during the cropping period was 521.7 mm received in 31 rainy days.Result: The field experimental results revealed that adoption of agronomic manipulation at the appropriate stage of the crop has increased the productivity of redgram. Nipping of primary branches at 45th day of the crop significantly increased the total number of productive branches, number of pods plant-1 and recorded the maximum seed yield of 1512 kg ha-1 (72 per cent increase over farmer’s practice) under rainfed condition.
