The present investigation "Impact of different broad spectrum herbicides on seed and stover yields of Chickpea Crop (Cicer arietinum L.)" was carried out during Rabi season in 2015-16 and 2016-17 at Instructional Cum Research Farm of IGKV, Raipur (Chhattisgarh). The soil of experimental field was clayey (Vertisols) in texture, locally known as "Kanhar" which was low, medium and high in available N, P2O5 and K2O, respectively. The experiment was laid out in Randomized block Design with three replications. The experiment conducted with Chickpea (Cicer arietinum L.) variety 'Vaibhav' was grown as test crop consists of eleven different herbicides treatment. It was found non significantly difference between plant population at 20 DAS and significance difference between at harvest stage during both the years and on mean basis. The maximum plant population at harvest was recorded under treatment weed free hand weeding at 20 and 40 DAS and minimum was recorded under weed check. Seed yield, stover yield and harvest index found significantly different between all the treatments. Treatment weed free (hand weeding at 20 and 40 DAS) recorded maximum seed yield (1806.27 kg/ha and 1994.40 kg/ha) and minimum (440.67 and 467.07) was in weedy check. Highest stover yield (2985.47 and 3124.4) was obtained under Pendimethalin 30 EC @ 1.0 kg ha -1 PE +one hand weeding at 30 DAS) while lowest under weedy check during both the years and on mean basis. Higher harvest index (39.95 and 40.66) recorded under weedy (hand weeding at 20 and 40 DAS) and minimum (18.60 and 18.66) under weedy check.
An experiment was conducted at Research cum Instructional farm, IGKV, Raipur, Chhattisgarh, India during kharif season of 2016 to assess the effect of different levels and sources of zinc application on growth, yield, zinc content and economics of rice. Nine treatments of zinc fertilization and one control (Without zinc) were allocated randomly in simple randomized block design and replicated thrice. Zinc content was estimated by using standard method described under Harvest Plus (2005) guidelines using Atomic absorption spectrophotometer (AAS200). The results revealed that maximum effective tillers was recorded with application of 50 kg ZnSO4 ha -1 in soil + Two foliar spray of 0.2% Zn through Zn-EDTA at panicle initiation (PI) and flowering (FL). Almost similar test weight and, grain (55.87 q ha -1 ) and straw yields (72.73 q ha -1 ) were recorded with application of 25 kg and 50 kg ZnSO4 ha -1 in soil each + Two foliar spray of 0.2% Zn through ZnSO4 and through Zn-EDTA at PI and FL stage and, with three foliar spray of 0.2% Zn through ZnSO4 at tillering, PI and FL stage. The maximum zinc content in grain and straw was observed with application of 50 kg ZnSO4 ha -1 in soil + Two foliar spray of 0.2% Zn through ZnSO4 at PI and FL. The maximum net returns (Rs. 65574 ha -1 ) and benefit cost ratio (2.60) were recorded with three foliar spray of 0.2% Zn through ZnSO4 at tillering, PI and FL stage.
