Productivity and soil moisture conservation studies of pigeon pea based intercropping systems as influenced by different land configurations

Abstract

A field experiment was conducted to study effect of various land configurations on soil moisture conservation and productivity of pigeonpea at experimental farm of AICRP for dry land Agriculture, V.N.M.K.V., Parbhani during kharif season of 2015 and 2016. Soil of experimental field was medium deep black with low in organic carbon, low in available nitrogen, medium in available phosphorus and high in available potassium.The experiment was laid out in split plot design with three main plot treatments and four sub plot treatments. The gross and net plot sizes are 7.2x5.4m2 and 5.4x3.6m2 respectively. The pigeonpea variety BDN-711 was used for sowing with spacing 90 x 20 cm. The main plot treatments were three land configurations as (L1) broad bed furrow (BBF), (L2) ridges and furrow and (L3) flat bed method. Sub plot treatments were four intercropping systems i.e. (I1) pigeonpea + soybean (2:1), (I2) pigeonpea + green gram (2:1), (I3) pigeonpea + black gram (2:1) and (I4) pigeonpea + cowpea (2:1). It was observed that seed yield of pigeon pea andpigeonpea equivalent yield were significantly affected due to different land configuration and intercropping systems. The highest pigeonpea seed yield (1588 kg ha-1) and pigeonpea equivalent yield (1823 kg ha-1) were obtained with Broad bed furrows (L1) followed by ridges and furrow (L2). Among the intercropping systems, pigeonpea + greengram intercropping system (I2) recorded higher seed yield (1574 kg ha-1) and pigeonpea equivalent yield(1832 kg ha-1).Periodical soil moisture observations in different land configuration considering depth of soil, higher average soil moisture was recorded under broad bed furrow followed by ridges and furrows while lesser was recorded under flat bed sowing.

Effect of Crop Establishment Methods and Weed Management Practices on Productivity and Profitability of Clusterbean under Semi-arid Region of Rajasthan

“…This might be due to the fact that under favourable soil conditions, the plant accumulates and translocates the photosynthates from source to sink more efficiently which in turn increased yield attributes and yield. Similar results of higher grain yield and straw yield were also reported earlier by Pandey et al, (2018) in blackgram, Garud et al, (2019) in pigeonpea and Halli and Angadi (2019) in cowpea also reported higher grain yield with broad bed method of sowing. All weed management practices had significant effect on yield of clusterbean as compared to weedy check.…”

Effect of Land Configuration and Weed Management on Performance of Urdbean [Vigna mungo (L.) Hepper]

“…Similar results of higher grain yield and straw yield were also reported earlier by Pandey et al (2018) in blackgram. Similarly, Garud et al, (2019) and Halli and Angadi S.S. (2019) also reported more grain yield in pigeonpea and cowpea, respectively with broad bed furrow method of sowing. W hereas, the maximum grain yield (1280 kg ha -1 ) was obtained with spraying of pendimethalin 30 EC @ 1.0 kg a.i ha -1 PE fb imazethapyr 10% SL @ 55g ha -1 at 15-20 DAS which was significantly more than other weed management practices (Table 2).…”
