A field experiment was conducted during 2003-04 and 2004-05 to asses the production potential of intercropping of cassava (Manihot esculenta L.) with groundnut (Arachis hypogea), vegetable cowpea (Vigna sinensis) and black gram (Vigna mungo) in relation to various weed control practices. Intercropping influenced the population of grasses, sedges, BLW and total dry matter production of weeds. Weed management caused significant improvement in growth, yield and economic returns of cassava system. Best results were achieved with intercropping of vegetable cowpea with pre-emergence application of fluchloralin 0.75 kg/ha + one hand weeding 4 weeks after planting followed by application of alachlor @ 1.5 kg/ha + one hand weeding 4 weeks after planting.Keywords

A field experiment was conducted to study the effect of partial shade, inorganic, organic and biofertilizers on biochemical constituents and quality of turmeric. The study was laid out in split plot design, consisting of two main plots viz., open and shade. The sub-plot treatments consisted of different doses of inorganic fertilizers, organic manures, biofertilizers and growth stimulants constituting of 40 different treatment combinations. The treatment combinations, viz., shade with application of 100 % recommended dose of NPK + 50 % FYM (15 t ha-1) + coir compost (10 t ha-1) + Azospirillum (10 kg ha-1) + phosphobacteria (10 kg ha-1) + 3 % panchagavya showed increased total chlorophyll content, total phenol content and registered the highest yield per plot. On the contrary, provision of shade decreased the curing percentage as compared to open condition. Among the quality characters, the highest curcumin (5.57 %) and essential oil (5.68 %) content were registered in the treatment, shade with application of 50 % FYM + coir compost + Azospirillum (10 kg ha-1) + phosphobacteria (10 kg ha-1) + 3 % panchagavya.Keywords
