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.
A field experiment was conducted at Department of Agronomy, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani during Rabi season of 2009-10 with a view to find out a response of different fertilizer levels and varieties on growth and yield of wheat and to find interaction effect of fertilizer levels and varieties. The results of study showed that the fertilizer level 120:60:60 kg NPK ha-1 was found beneficial in improving growth characters, yield attributes and yield as compared to 80:40:40 kg NPK ha-1 , 100:50:50 kg NPK ha-1 and 150:75:75 kg NPK ha-1 under late sown condition. Variety Lok-1 proved to be superior in growth characters, yield attributes and yield as compared to SKFPS-645 and NIAW-34 under late sown condition.
Background: Pigeonpea being highly branching and indeterminate growth habit responds very well to crop geometry. Hence to achieve potential yields, it is important to maintain optimum plant population which can effectively utilize available moisture, nutrients and solar radiation. The plant growth regulators are also known to enhance the source sink relationship and stimulate the translocation of photo assimilates, thereby increase the productivity.
Methods: A field experiment was conducted at experimental farm of Agronomy Department, V.N.M.K.V., Parbhani during kharif season of 2018 and 2019. The experiment was laid out in split plot design with four main plot treatments comprised of four crop geometries as 90 cm x 20 cm, 120 cm x 20 cm 60-120 cm x 20 cm and 75-150 cm x 20 cm and sub plot treatments were five treatments on foliar application of plant growth regulators i.e. NAA @ 40 ppm, Mepiquat chloride @ 50 g a.i. ha-1, Brassinosteroids @ 0.1 ppm, Chlormequat Chloride @ 75 g a.i ha-1 and control.
Result: The crop geometry of 120 cm x 20 cm and 75-150 cm x 20 cm recorded higher values of all yield parameters followed by crop geometry of 60-120 cm x 20 cm. While the seed, straw and biological yield of pigeonpea as well as highest net realization of Rs. 72072 ha-1 was obtained with crop geometry of 60-120 cm x 20 cm followed by 90 cm x 20 cm. Among the plant growth regulators foliar application of Brassinosteroids @ 0.1 ppm (G3) tended to recorded higher yield parameters, seed yield and fertility coefficient of pigeonpea as well as highest net realization followed by foliar application of NAA @ 40 ppm.
