The experiment was laid out in a randomized block design with ten treatment combinations viz., Absolute Control, Generalised Recommended Dose of Fertilizer (GRDF) 100: 50: 50 N P2O5 K2O Kg ha-1 + FYM 25 t ha-1, As per Soil Test, STCRC target for 250 q ha-1 without vermicompost, STCRC target for 300 q ha-1 without vermicompost, STCRC target for 350 q ha-1 without vermicompost + Biofertilizer, STCRC target for 250 q ha-1 with vermicompost, STCRC target for 300 q ha-1 with vermicompost, STCRC target for 300 q ha-1 with vermicompost + Biofertilizer, Only 5 t ha-1 vermicompost. The research findings revealed that treatment T9 resulted in a significantly higher number of leaves (8.56 and 11.52) at 40 and 80 days after transplanting (DAT), height of crop (42.00 and 57.46 cm) at 40 and 80 days after transplanting (DAT), Chlorophyll (41.30 and 51.84) at 45 and 60 days after transplanting (DAT), polar and equatorial diameter (6.36 and 9.48 cm), neck girth (4.94 cm) and bulb weight (64.09 gm). Similarly, the treatment T9- STCRC target for 300 q ha-1 with vermicompost + Biofertilizer achieved significantly superior bulb yield (363.67 q ha-1) with per cent deviation of 3.90 % and top yield (67.18 q ha-1).

In India, sweet corn is cultivated on very small area to meet the demands of many industries. The demand for eating roasted cobs in cities and towns is increasing day by day. Sweet corn is gaining popularity among the urban masses in terms of nutrition and health consciousness in India. Heavy weed infestation is one of the major constraints that limit the productivity of sweet corn crop. Wider spacing and slow growing nature of the crop during the first 3-4 weeks provide enough opportunity for weeds to invade and offer severe competition resulting in 30-100 % yield reduction (Dey et al., 2017). Weeds emerge fast and grow rapidly competing with the crop for growth viz., nutrients, moisture, sunlight and space during entire vegetative and early reproductive stages of sweet corn.

The weed free treatment (T2) with two hand weeding recorded significantly higher total N, P and K uptake of 253.16, 84.36 and 259.13 kg ha, respectively, by sweet corn. However, significantly lower total N, P and uptake of 104.60, 31.98 and 109.94 kg ha, respectively, by sweet corn was recorded in the treatment of weedy check (T1). Among the treatments of pre and post emergence herbicides, application of pendimethalin @ 1000 g ha as pre emergence fb tembotrione @ 120 g ha as post emergence (T6) recorded higher total N uptake (230.22 kg ha), P uptake (72.37 kg ha) and K uptake (240.85 kg ha) by sweet corn with 120, 126.29 and 119.07 % increase, respectively, over the treatment of weedy check (T1) and 9.06...

The soil physical properties viz. hydraulic conductivity, mean weight diameter and soil chemical properties viz. soil pH, electrical conductivity, available N in soil, available K in soil were significantly influenced in the treatment of 100% RDN through FYM as compared to the treatment receiving 100% RDF through inorganic fertilizers at the end of 6 th cycle of pearl millet-chickpea cropping sequence. The hydraulic conductivity (0.64 mm hr-1) and mean weight diameter (0.61 mm) were significantly increased in the treatment of 100% RDN through FYM (T3). The soil pH (7.40) and electrical conductivity (0.33 dSm-1) were significantly decreased and soil available N (244 kg ha-1) and K (273 kg ha-1) were significantly increased in the treatment of 100% RDN through FYM (T3) as compared to the treatment receiving 100% RDF through inorganic fertilizers (T2).
