A transition period of at least two years is required for annual crops before the produce may be certified as organically grown. The purpose of this study was to evaluate the effects of the three organic amendments on yield and quality of wheat (Triticum aestivum L.) and on soil properties during transition to organic production. The organic amendments were composted farmyard manure (FYMC), vermicompost and lantana (Lantana spp. L.) compost applied to soil at four application rates (60, 90, 120 and 150 kg N ha-1). The grain yield of wheat in all the treatments involving organic amendments was markedly lower (36-65 % and 23-54 % less in the first and second year of transition, respectively) compared with the mineral fertilizer treatment. For the organic treatments applied at equivalent N rates, grain yield was higher for FYMC treatment closely followed by vermicompost. In the first year of transition, protein content of wheat grain was higher (85.9 g kg-1) for mineral fertilizer treatment whereas in the second year, there were no significant differences among the mineral fertilizer treatment and the highest application rate (150 kg N ha-1) of three organic amendments. The grain P and K contents were, however, significantly higher for the treatments involving organic amendments than their mineral fertilizer counterpart in both years. Application of organic amendments, irrespective of source and rate, greatly lowered bulk density (1.14-1.25 Mg m-3), and enhanced pH (6.0-6.5) and oxidizable organic carbon (13-18.8 g kg-1) of soil compared with mineral fertilizer treatment after two-year transition period. Mineral fertilized plots, however, had higher levels of available N and P than plots with organic amendments. All the treatments involving organic amendments, particularly at higher application rates, enhanced soil microbial activities of dehydrogenase, -glucosidase, urease and phosphatase compared with the mineral fertilizer and unamended check treatments. We conclude that the application rate of 120 and 150 kg N ha-1 of all the three sources of organic amendments improved soil properties. There was, however, a 23-65% reduction in wheat yield during the two years of transition to organic production.

Randomized Block Design

A field trial was conducted to assess the effect of organic inputs and bioagents on growth, yield, and quality of okra. Thirteen treatments in the experiment were laid out in Randomized Block Design with three replications. The results revealed that the yield parameters were best in conjoint application of organic and inorganic fertilizer whereas the physical and quality parameters showed a maximum in integrated application of organic amendments and bioagents. On the basis of the findings it may be concluded that FYM @ 20 t/ha + VAM + Pseudomonas + Trichoderma + Azotobacter resulted the highest B: C ratio (2.66) and can be recommended as substitute for the inorganic combination of FYM @ 10 t/ha + 50:50:50 kg NPK/ha for higher quality yield with remunerative return.

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.
