The Impact

Aim: To determine the impact of soil and foliar application of ZnSO4.7H2O at late stages of wheat as heading initiation (5% ear formation), 100% heading (complete ear formation) and heading initiation and 100% heading along with recommended dose of fertilizer on growth, yield and quality of zero till wheat. Methodology: The field experiment was conducted on zero till wheat. The treatments consisted of control (no Zn), soil application of 12.5, 25, 37.5, 50 kg ha-1 ZnSO4.7H2O and foliar application of 0.5% Zn as one spray at heading initiation (5% ear formation), one spray at 100% heading (complete ear formation) and two sprays at heading initiation and 100% heading with recommended dose of fertilizer. These treatments were evaluated in RBD with three replications. Results: Soil application of 50, 37.5 and 25 kg Zn ha-1 with two foliar sprays of 0.5% at heading initiation (5% ear formation) and 100% heading (complete ear formation) stages gave significantly higher average grain and straw yield and Zn concentration in grain than other treatments, including control. Interpretation: Enhanced application of Zn as soil and foliar application ameliorates soil Zn deficiency and increases protein content in grains, which might influence the quality and yield of zero tilled wheat.

A field experiment was carried out at College Farm, Navsari Agricultural University, Navsari on clayey soils during summer season of the year 2019 to study the Effect of iron and zinc on growth, yield and quality of cowpea (Vigna unguiculata L.) under south Gujarat condition. The results of experiment indicated that growth and yield attributes viz., plant height at 60 DAS and at harvest, number of branches per plant, number of nodules per plant, number of pods per plant, pod length, seed and haulm yield (955 and 2008 kg/ha, respectively) and test weight increased significantly with soil application of FeSO4 @ 25.0 kg/ha which was significantly higher over control but remained at par with soil application of 12.5 kg FeSO4/ha. Similarly zinc is also an essential plant nutrient for plant growth and yield. Zinc application had also positive effect on growth and yield attributes viz., plant height at 60 DAS and at harvest, number of branches per plant, number of nodules per plant, number of pods per plant, pod length, seed and haulm yield (972 and 2030 kg/ha, respectively) and test weight increased significantly with soil application of ZnSO4 @ 25.0 kg/ha which was significantly higher over control but remained at par with soil application of 12.5 kg ZnSO4/ha. Significant improvement in protein content in seed with soil application of both FeSO4 and ZnSO4 @ 25.0 kg/ha.

Abstract Onion is an important crop with significant roles in human diets. The growth, yield, and quality of vegetable crops, including onions, are more vulnerable to water stress than other crops. In this study, different levels of deficit irrigation (DI) as factor A (a1: 80%, a2: 70%, and a3: 60% of soil field capacity [FC]) and humic acid (HA) as factor B (b1: without and b2: with HA application) were evaluated on onion growth characteristics in a factorial design with four replications. The results showed that the interaction of DI and HA was significant on leaf protein, peroxidase (POD), superoxide dismutase (SOD), and on bulb protein and potassium (K) concentrations. The highest record of these traits was observed in a3b2 (highest DI with HA application), and their lowest was in those at first level of DI (a1). Leaf protein and, to a lesser extent, bulb protein were increased by DI and HA applications. DI at 60% but not at 70% FC significantly reduced bulb fresh weight. There was a gradual increase in leaf proline, soluble sugars, protein, catalase (CAT), POD, SOD activity, and bulb K by application of DI; however, most of bulb traits including protein, iron (Fe), zinc (Zn), and CAT and POD activity were increased only under highest DI level (a3: 60% FC). However, application of HA further increased the soluble sugars and protein concentration as well as the POD and SOD activities of leaves, and protein, Fe, K concentrations, and CAT activity of bulbs under DI. The results indicated that HA benefitted onion growth particularly under DI conditions.

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.
