Yield And Quality

Proper nutrition is one of the factors which is limiting onion production. Onion yield and quality is affected by fertilization of macro and micro nutrients. Mineral nutrients, Nitrogen, phosphorous and Potassium are macronutrients which significantly affect onion production. Nitrogen and phosphorous fertilization significantly affect growth, yield and quality of onion. The requirement of mineral fertilizer varies from place to place, depending on different factors in the growing areas. Effective use of N, P and K fertilizer depends on soil condition, irrigation system, climatic factors and management factors. In all different research reports, it is described that onion is a heavy feeder for N, P, K and the application of these mineral elements enhance production significantly. The quality of onion, physiology and production is highly limited by fertilization of N, P and K fertilizers. Therefore, in this review the effect of mineral nutrition on growth, physiology and yield of onion are discussed and examined in detail.

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.

Mineral nutrients are essential to plant growth and development. The present study aimed to evaluate the effects of mineral fertilizer doses and N:P:K ratio on growth, yield, and raw material quality of the tea variety PH10 to improve the production of high-quality tea products. The field experiment was conducted from 2015 to 2017. A two-factor experiment was designed by split-plot design with three replications. The mainplot treatments were three fertilizer doses of N  for one metric ton of fresh shoot products (30, 40, and 50 kg N ha-1). The subplot treatments were two NPK ratios (3:1:1 and 3:1:2). Plant height, leaf canopy, plant diameter, shoot yield parameters, shoot components, biochemical compounds, and sensory quality for Oolong and Sencha tea products were evaluated. The results showed that increasing fertilizer doses from 30 up to 40 kg N per ton of fresh product improved remarkably growth, yield, and tea quality of PH10 variety. Different fertilizer ratios resulted in variations in plant growth, the content of carbohydrate, sensory quality for taste and flavor as well as total sensory quality with higher values at NPK ratio of 3:1:2. Applying mineral fertilizer with an NPK ratio of 3:1:2 and 40kg N per ton of fresh shoot products was recommended to bring about the most benefits of tea yield and quality as well as economic profit.

Goat Manure

This study aims to improve the growth, yield, and quality of LP-VoS bulbs by applying bokashi fertilizer from goat manure and regulating the duration of water supply with a sprinkler irrigation system. This research is a field that arranged in split-plot design. The main plot is the duration of irrigation water supply, consisting of three levels, 0.5; 1,0; and 1.5 hours. The subplot is giving organic fertilizer bokashi goat manure, which consists of two kinds, namely: without bokashi fertilizer and the addition of bokashi fertilizer 15 t.ha-1. Each treatment was repeated three times so that in total, there were 18 experimental plot units. The results showed that the duration of irrigation 0.5 hours at intervals of 3 days, followed by the application of 15 t.ha-1 bokashi organic fertilizer could increase the bulb circle of 'Lembah Palu' varieties.The use of bokashi organic fertilizer 15 t.ha-1 could increase soil moisture so it can growth, yields, and quality of shallot bulb. The duration of irrigation with a sprinkler system for 0.5-1.0 hours at intervals of 3 days could result in the growth of total dry weight and total leaf area per plant as well as the number of tubers per clump, fresh weight of tubers per clump and yield of tubers per hectare higher than treatment of water for 1.5 hours at intervals of 3 days. Water supply regulations and the use of bokashi organic fertilizers can increase the growth, yield, and quality of LP-VoS bulbs on dryland. For the cultivation of‘Lembah Palu’ varieties of shallots in dry land, it is necessary to apply organic fertilizers to increase the soil water content for increased production and quality.
