Aim: To investigate the integrated use of chemical fertilizer and potential tasar silkworm (Antheraea mylitta) excreta as fertilizer on the growth, yield and quality of rice.. Methodology: A pot experiment was designed in Completely Randomized Design with four replicates with nine treatments, where Terminalia arjuna leaf litter, tasar silkworm excreta and recommended dose of chemical nitrogen fertilizer at 25%, 50% or 100% alone or in combinations was applied in transplanted rice plants. The observations were recorded for different growth parameters at 30, 60 and 90 days interval, while yield traits were recorded at the time of crop harvest. Results: Leaf litter and tasar silkworm (Antheraea mylitta Drury) excreta on growth, yield and quality of rice revealed that application of 100% recommended dose of nitrogen (RDN) from tasar silkworm excreta recorded significantly higher plant height, panicle length, number of grains panicle-1 and 1000 grain weight at rice harvest. While, chlorophyll index, grain yield, number of effective tillers per hill, biological and protein yield of rice recorded significantly higher in 75% recommended dose of nitrogen through chemical nitrogen fertilizer + 25% recommended dose of nitrogen from tasar silkworm excreta. Nitrogen and protein content of grain recorded statistically higher in 50% recommended dose of nitrogen through inorganic fertilizer + 50% RDN from tasar silkworm excreta. Grain yield was significantly correlated with nitrogen uptake and protein yield, plant height, effective tillers per hill, 1000 grain weight, straw and biological yield. Interpretation: Integrated use of 75% RDN through chemical nitrogen fertilizer with 25% RDN from tasar silkworm excreta is suitable for higher production that may reduce the external input of chemical nitrogen fertilizers and promote zero waste management.

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.

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.
