A study was undertaken to assess the effect of different seasons, additives and grass types on silage quality at AICRP on Forage Crops and Utilization, College of Agriculture, Vellayani, Kerala during Rabi 2015-16. Pooled analysis of the data over two seasons was done and perusal of the data showed that seasons had no significant influence on quality parameters of silage. But grass type had significant influence on dry matter content, total ash and crude protein content of silage. Individual effect of additives was significant on total ash and acid insoluble ash. Highest crude protein content was recorded in the silage prepared from BN hybrid+ Jaggery 2% and it was on par with BN hybrid+ Urea 1% and BN hybrid+ Tapioca flour 1%.

Home gardens are a time tested food production system which can be projected as a promise to the future to mitigate the issues related to the global food security crisis. The home gardens in Kerala are an integral part of the rich tradition which impart a dominant role in livelihood security of the people. The diversity profile of traditional homegardens of high range area and its spatial patterns were investigated in the present study revealed that a mean Shannon and Wiener diversity index (H) of 2.185 was recorded which denoted a dwindling trend in species diversity in banana based high range home gardens of Idukki. An appraisal of the diversity of crops revealed that the highest diversity was recorded in spices (H=1.425) and was on par with fruit crops (H=1.339) whereas lowest was noted on fodder crops (H= 0.054) followed by medicinal plants (H=0.197). Furthermore, the mean total diversity index exhibited a positive significant correlation with the total area of the home garden w...

Agricultural, industrial, and techno-socio-cultural intervention by man had an influence on the quality of the river water and its tributaries. Contemporary agriculture practices reveal and augment the use of pesticides to meet the food security and to satisfy the needs of surging population which results in contamination of the aquatic environment. In the pursuit to achieve maximum crop production, pesticide use has played a major role and has resulted in the accumulation of pesticide residues deemed to be highly detrimental to aquatic and related ecosystem. This study funded by Kerala State Council for Science, Technology and Environment was aimed at understanding the extent of pesticidal residues and pollution of water bodies in the riparian tributaries of Chalakkudy river. The efforts to assess the quality of water in the Chalakkudy tributaries confirmed the presence of pesticide residues of quinalphos and ethion (0.21-2.90 µgL-1) through chemical analysis in 41.18% of total num...

Rice, which plays an important role in providing food to the majority of the world population, is cultivated in a wide range of ecosystems. In India, out of the 42.7 million ha of land under rice, about 21.9 percent of the area is exposed to risk prone upland ecology (Mishra, 1999). The productivity of the upland rice is very low because of a host of problems among which soil moisture stress, poor native soil fertility and heavy weed infestations are the important ones. Under upland situation, moisture stress is likely to occur during any of the growth stages of the crop which may adversely affect the growth and yield. The yield of rice under upland situation can be increased by judicious management of production inputs.

Background: India ranks first in global livestock production and it is an important subsidiary enterprise that support more than 75 per cent of the rural community. But fodder production is not well practiced in our country and animals generally consume naturally grown grasses and shrubs which are of low quality in terms of protein and available energy. Hence, there is an urgent need to look for new fodder resources that are sustainable in nature and cover our fodder deficit. Keeping the above in view, the present study has been proposed to evaluate the predominant tree fodders and shrubs of Southern Kerala as a quality livestock feed. Methods: The study was conducted in College of Agriculture, Vellayani, Thiruvananthapuram during January-September, 2020 to assess the nutritional value of predominant tree fodders and shrubs in Southern Kerala as a quality feed for cattle. Ten different fodder trees and shrubs that locally fed to the cattle viz., Agathi (Sesbania grandiflora), erythr...

Field experiments were conducted to compare the System of Rice Intensification (SRI) with the best management recommendations and farmers’ practices of rice ( Oryza sativa L.) production. The experimental variables included combinations of seedling number and age (10 day-old single vs. 20 day-old two seedlings per hill), spacing (25 x 25 cm vs. 20 x 15 cm), irrigation (intermittent irrigation vs. continuous flooding), and weed control (cono-weeding vs. manual weeding) treatments, besides farmers’ practice (control). The trial was laid out in completely randomized factorial design, replicated thrice. Highest grain yield (4467 kg ha–1) and net returns (Rs 17745 ha–1) were obtained for the suite of best management practices (planting two 20 days-old seedlings hill–1 at 20 x15 cm + intermittent irrigation and cono-weeding). Yield under SRI management (planting 10 day-old single seedlings at 25 x 25 cm + intermittent irrigation and cono-weeding: 3326 kg ha–1) was lower than that of recom...

Farm management is one of the most decisive factors in production and marketing of agricultural crops. In a broad depiction, management is defined as making decision process through which the limited resources are allocated to competent items in such a way that the determined goal can be achieved. Mathematical programming especially linear programming supports farmers for efficient decisions in the field of allocating limited resources to competent activities. This research paper was carried out with the objectives of examining and developing statistical models for homestead farming systems in the southern laterite agro-ecological units (AEU8) of Thiruvananthapuram District and to suggest suitable cropping/farming system models that maximize farm income by the optimal use of available resources. The optimum model worked out for SI (crop only) in AEU8 consisted of binding solution for almost all the enterprises except some enterprises like coconut and banana with 25.30 per cent enhancement in net return as compared to net return from the existing plan. The optimum model for S2 HFS was also similar to that of S1 with non-binding solution for coconut and poultry with 31.30 per cent increase in net return. However, sensitivity analysis of the optimum model revealed that further enhancement of net return could be achieved by increasing the cropping intensity in the underutilized intercropped area and changing the binding enterprises.
