Evaluation of chickpea varieties under compartmental bunding in rainfed situation

Abstract

Compartmental bunding (CB) and improved chickpea varieties were evaluated in ten farmers' fields during rainy-winter (kharif-rabi) seasons of 2012-13 in Vertisols at Bellary, India. Adopting improved chickpea varieties of BGD103 and JG11 during winter season increased the grain yields from 12.5 to 15.9%, respectively over locally cultivated A1 variety. The CB that was laid out during July (rainy season) conserved rainwater in-situ and further increased the grain yield of chickpea up to 36.7% in BGD103 and 43.9% in JG11. The increase in grain yield from 24.2% (JG11) to 27.8% (BGD103) indicates that CB is effective for in-situ rainwater conservation and improving profile soil moisture in Vertisols. However technology gap during study period was higher compared to extension gap and it was attributed to drought situation with only 81.2% of mean annual rainfall. Technology index was higher in this study and varied from 48.3% (Cultivation of BGD103 variety with CB) to 60.6% (Cultivation of JG11 variety without CB) indicating that technology index can be reduced and chickpea yields can be increased and sustained with adoption of improved chickpea production technologies including in-situ rainwater conservation practices at farmers fields. Correlation studies also indicate that grain weight, stover weight and total dry matter production per plant ultimately determine the chickpea grain and stover yields in the Vertisols of Bellary region during winter season. Higher gross and net returns with greater B:C ratio was observed with layout of farmers fields with CB and cultivation of JG11 variety.

Biochemical basis of resistance in chickpea varieties against Callosobruchus chinensis Linn. (Coleoptera: Bruchidae)

“…All the varieties of chickpea showed relative behavior to C. chinensis, but the varieties BG 1053, PKG 1 and BG 1003 with less flavonoids content had high growth index as compared to moderately susceptible varieties (PG 4, PG 186 and PKG 2) and moderately resistance varieties (PBG 1, BGM 547 and PG 114) which showed less growth index because of the presence of high flavonoids which affect their metabolic activity and inhibit their growth. (Patil et al, 2016;Southgate, 1979).…”

Impact of improved production technologies on chickpea yields, economics and energy use in rainfed Vertisols

“…Availability of micronutrients in the soil was more efficiently utilized by drought tolerant JG11 variety and produced higher yields (Table 2). Earlier studies at Bellary indicated that (Thyagaraj, 2012) improved varieties of chickpea, i.e., JG11 and BGD103 produced higher yields more returns during both drought and normal years over other varieties evaluated (Patil et al, 2014(Patil et al, , 2015(Patil et al, and 2016. Chickpea cultivation was most profitable as it grows on low fertile soils under low moisture situations (Ahlawat et.…”

“…The increased yields with IP-III were attributed to better plant growth with higher dry matter production and its translocation to the reproductive parts. Moreover cultivation of JG11 produced more yields over the traditional farmers' cultivated A1 variety (Patil et al, 2014(Patil et al, , 2015(Patil et al, and 2016. Application of micronutrients improved the chickpea yields as these soils are low in micronutrients.…”

“…2013;Gowda, et al, 2015;Singh et al, 2015). In south India chickpea is cultivated under receding soil moisture during winter season in the Vertisols with low productivity due to cultivation of traditional variety (Patil et al, 2014(Patil et al, , 2015(Patil et al, and 2016.…”

Temperature Induction Response (TIR) - A novel physiological approach for thermotolerant genotypes in chickpea (Cicer arietinum L.)

“…Drought stress coupled with high temperature is associated with reduced water availability and cellular dehydration alters the cellular metabolism coupled with osmotic adjustment (Suruchi khanna et al 2016). Development of genotypes that are capable to survive better under high temperature stress and drought is paramount important and inevitable and cultivation of pulses in scarce soil moisture during winter season has remained a major challenge for enhancing the productivity for decades (Patil et al 2016).…”
