Effect of Waterlogging Duration at Different Growth Stages on the Growth, Yield and Quality of Cotton

Background: Productivity of cowpea in our country is very low. So, there is need to take proper agronomic practices to enhance the productivity of cowpea and foremost important among them is foliar application of organic and inorganic sources of nutrients exploiting genetic potential of crop. This is considered to be an efficient and economic method of supplementing part of nutrient requirement at critical growth stages of the crop. Foliar application is credited with the advantage of quick and efficient utilization of nutrients, elimination of losses through leaching, fixation and regulating uptake of nutrients by the plant. In view of above consideration, the experiment entitled “Influence of foliar application of different organic sources on growth, yield and quality of cowpea (Vigna unguiculata L.) under varying levels of fertilizer” was conducted with objectives to study the effect of different levels of fertilizer on growth, yield and quality of cowpea, to study the effect of foliar application of different organic sources on growth, yield and quality of cowpea, to study the interaction effect of different levels of fertilizer and foliar application of organic sources and to study the economics of different treatments. Methods: The field experiment was conducted at Agronomy Farm, College of Agriculture, Dapoli, Dist. Ratnagiri (M.S.) during Rabi 2019-20. Field experiment was laid out in factorial randomized block design. The fertilizer levels comprised of three levels viz., F1: 100% RDF, F2: 75% RDF and F3: 50% RDF and foliar application consisted of five different organic sources viz., S0: Control, S1: Panchagavya @ 3%, S2: Vermiwash @ 10%, S3: Cow urine @ 5% and S4: Vasant urja @ 0.5%. There were 15 treatment combinations replicated three times. Result: It can be concluded that for growing cowpea, it should be supplied with 100% RDF and sprayed with panchagavya @ 3% or cow urine @ 5% foliar application, so as to obtain higher yield and economic returns.

Randomized Block Design

The present investigation was undertaken with an objective to understand the effect of municipal solid waste (MSW) vermicompost and compost on growth, yield and quality of chickpea. The experiment was laid in randomized block design with three replications and seven treatments viz, T1 - RDF, T2 - RDF + vermicompost of MSW @ 2.5 t ha-1, T3 - RDF + vermicompost of MSW @ 5 t ha-1, T4 - RDF + vermicompost of MSW @ 7.5 t ha-1, T5 - RDF + compost of MSW @ 2.5 t ha-1, T6 -compost of MSW @ 5 t ha-1, T7 -compost of MSW @ 7.5 t ha-1. The field experiment was conducted at College of Agriculture, Latur farm during the Rabi season 2016-2017. The recommended dose of fertilizer (25:50:00 N: P: K) and MSW vermicompost and compost was applied at the time of sowing. The results of field experiment revealed that the maximum availability of macro and micronutrients in soil, growth attributes viz. plant height and number of branches in all growth stages of chickpea were found at application of 7.5 tones of MSW vermicompost ha-1 along with 100% RDF (25:50:00 NPK) followed by application of 7.5 tones MSW compost ha-1 along with 100% RDF and which was significantly increased with increased levels of MSW vermicompost and compost. Similar trend was observed in case of yield and quality parameters viz., protein content of chickpea.

Yield And Quality

Water pumping restrictions of high-quality irrigation water from underground aquifers is affecting vegetable production in Southwest Texas. There is a need to develop efficient deficit-irrigation strategies to minimize irrigation inputs and maintain crop profitability. Our objective was to determine how growth, yield, and quality of cantaloupe (Cucumis melo L. cv. `Caravelle') are affected by irrigation systems with varying input levels, including drip depth position and polyethylene mulch. Stand establishment systems used were containerized transplants and direct seeding. Field experiments were conducted on a Uvalde silty clay loam soil. Marketable yields increased in the order of pre-irrigation followed by: dry-land conditions, furrow/no-mulch, furrow/mulch, drip-surface (0 cm depth)/mulch, drip-subsurface (10-cm depth)/mulch, and drip-subsurface (30 cm depth)/mulch. Pooled across all drip depth treatments, plants on drip had higher water use efficiency than plants on furrow/no-mulch or furrow/mulch systems. Transplants with drip-surface produced 75% higher total and fruit size No. 9 yields than drip-subsurface (10- or 30-cm depth) during the first harvest, but total yields were unaffected by drip tape position. About similar trends were measured in a subsequent study except for a significant irrigation system (stand establishment interaction for yield. Total yields were highest for transplants on drip-subsurface (10-cm depth) and direct seeded plants on drip-subsurface (10 and 30 cm depth) with mulch.

Yield And Quality

In agricultural production, nitrogen loss leads to economic loss and is a high environmental risk affecting plant growth, yield, and quality. Use of the N fertilizer with a urease inhibitor is thus necessary to minimize N losses and increase the efficiency of N. This study aimed to evaluate the effects of N-(n-butyl) Thiophosphoric Triamide (NBPT) on the growth, yield, and quality of pineapple. The experiment involved two foliar fertilizer treatments: 1% (w/v) urea solution with NBPT (2.25 mL kg−1 urea) was treated as NLU (NBPT Liquid Urea), and the same concentration of urea without NBPT served as the control. Both were applied 12 times, starting 1 month after planting (MAP) and continuing once a month for 12 months. The application of urea with NBPT notably increased the above-ground dry biomass per plant (20% and 10% at 8 and 12 MAP, respectively), leaf area per plant (23% and 15% at 8 and 12 MAP, respectively), N accumulation per plant (10%), PFPN (Partial Factor Productivity) (13%), and average fruit weight (15%) compared to the treatment with urea alone (control). The analysis of quality parameters indicated that urea with NBPT improves TSS (Total Soluble Solids) (19%), ascorbic acid (10%), and sucrose (14%) but reduces the total organic acid content (21%) in pineapple. When using urea with a urease inhibitor (NBPT), there was a significant improvement in growth, yield, quality, and nitrogen use efficiency, with the additional benefit of reduced nitrogen losses, in combination with easy handling. Hence, urea with a urease inhibitor can be used as a viable alternative for increasing pineapple yield by boosting growth with better fruit quality.
