During the kharif season of 2018, a field experiment titled "Influence of phosphorus and potassium in combination with biofertilizers on growth of cowpea [Vigna unguiculata (L.) Walp]" was carried out at the crop research farm of the Division of Agronomy, Faculty of Agriculture, Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir. The soil in the experimental field had the texture of clay loam, was neutral in reaction (pH 6.9), had low available nitrogen, low available phosphorus, medium available potassium, and medium organic carbon. The experiment was laid out in Randomized Block Design (RBD) design with nine treatments and three replications. The results of the experiment revealed that growth of the crop was significantly influenced by different treatments and Among various treatments, application of RDF (30 N, 60 P2O5, 30 K2O) kg ha-1+ seed inoculation with Phosphorus Solubilizing Bacteria (PSB) + Potassium Solubilizing Bacteria (KSB) significantly recorded maximum plant height (86.18 cm), leaf area index (3.62), dry matter production (16.20 q ha-1) and it also significantly increased the number of effective root nodules per plant of cowpea.
A field experiment was conducted during Kharif 2020 at Dry land Agriculture Research Station, Rangreth, Srinagar, Kashmir on Precision Nitrogen Management for enhancing fodder yield and nitrogen use efficiency in forage maize variety SFM-1 (KDFM-1) planted in a spacing of 30 x10 cm. The treatments consisted of T1 (No N), T2 50 kg N/ha (40% N basal) + remaining based on SPAD meter critical value of 40, T3 50 kg N/ha (40% N basal) + remaining based on SPAD meter critical value of 50, T4 50 kg N/ha (40% N basal) + remaining based on LCC 4, T5 50 kg N/ha (40% N basal) + remaining based on LCC 5, T6 100 kg N/ha (40% N basal) + remaining based on SPAD meter critical value of 40, T7 100 kg N/ha (40% N basal) + remaining based on SPAD meter critical value of 50, T8 100 kg N/ha (40% N basal) + remaining based on LCC 4, T9 100 kg N/ha (40% N basal) + remaining based on LCC 5, T10 150 kg N/ha (40% N basal) + remaining based on SPAD meter critical value of 40, T11 150 kg N/ha (40% N basal) + remaining based on SPAD meter critical value of 50, T12 150 kg N/ha (40% N basal) + remaining based on LCC 4, T13150 kg N/ha (40% N basal) + remaining based on LCC 5, T14 As per recommended package of practices (50% N as basal, remaining 50% at 30 days after sowing).The treatments were replicated thrice in a randomized block design. The results recorded during the year indicated that production of fodder maize was better with the treatment T13 (150 kg N/ha (40% N basal) + remaining based on LCC 5. It recorded 470.01 q green and 135.02 q dry matter yield per hectare. The growth parameters namely; plant height; number of leaves per plant and quality were also improved with this treatment as compared to other treatments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
