TRADE-OFFS BETWEEN FORAGE YIELDS AND FEED QUALITY OF LABLAB PURPUREUS, AND MILK YIELDS IN RELATION TO PLANTING AND HARVESTING SCHEDULES

This study, designed to investigate trade-offs between forage yields, feed quality and labour use in fitting a newly introduced crop, Lablab purpureus, into an existing farming system, adopted distinct applied and adaptive research approaches. The applied research component compared forage yields, nutrient contents and feeding qualities of L. purpureus harvested at 100, 114, 128 or 142 d after planting in an on-farm trial. The adaptive research investigated how farmers incorporated L. purpureus cultivaton into their farming calendars given the constraints of labour for planting and harvesting.Harvested dry matter yields from the on-farm experiment were 1.28, 1.98, 1.74 and 1.44 t ha−1. The resultant hays were fed to four groups each of five Bunaji lactating cows in an on-farm feeding trial over a 10-week period. Ranking the various harvests for yield, the hays for feed value, animal responses to the feed consumed and the quality of animal products on a linear scale (1 to 4) to estimate a composite utility index, showed that harvesting at 114 d after planting gave the most desirable overall benefits.The survey for adaptive research showed bimodal rainfed and irrigated cultivation patterns for L. purpureus. Peaks were observed in September (31% of farmers) and November (24%) for planting, and in December (39.4%) and March (15%) for harvesting. Forage yields were, however, highest for the 3% of farmers who afforded labour to plant in July and harvest in October. The lack of congruence between highest forage yield periods and the peaks of cultivation of L. purpureus by farmers in the study area was mostly explained by very significant differences in the cost of hired and household labour in different months. Thus, socio-economic and cultural factors, including stakeholders' participation, need to be considered along with applied research results when recommending forage species for farmers' adoption.

Forage Yields

Grain and forage production of six accessions (Rongai, Highworth, T58/ 13, CPI 3 1 1 13, CPI 41 222 and CPI 60 216) of lablab bean (Lablab purpureus) were measured over two seasons in the Ord Irrigation Area. All accessions were quantitative short day plants, flowering during the early dry season (May-July). Forage yields at flowering were generally unaffected by sowing date for sowings made between December and February, but declined with later sowings. There were marked differences between accessions in the forage yield at flowering, and the peak yield of 8.6 t/ha was obtained with a December sowing of accessions T58/ 13; this comprised 3.6 t/ha of leaf containing 3.7% nitrogen and 5.0 t/ha of stem containing 1.1 % nitrogen. The uptake of nitrogen by the tops between sowing and flowering ranged up to 1.8 kg/ha.d (1 94 kg N in 108 days) indicating the potential value of lablab as a green manure crop. Grain yields ranged from 0.27 to 3.05 t/ha over all sowing dates and accessions with the peak yield being obtained in a February sowing of cv. Highworth. All accessions became smaller and bushier as sowing was delayed. This facilitated harvesting for grain. Cutting and removal of foliage at the onset of flowering led to rapid regrowth and renewed flowering, and gave grain yields up to 90% of those obtained from undefoliated treatments. The cultivar Highworth was best for grain production and for dual purpose forage and grain production.

ABSTRACTThis study aims to determine the level of productivity of broilers in the partnership farm system in relation to the quality of feed provided by partner companies. The research was conducted in 2 (two) stages; Phase I. Survey of feeding system in partnership system of broiler farming in West Lombok. The parameters observed included: type of feed offered, the amount provided and frequency of feeding, harvest weight, and FCR. Phase II. Evaluation of the chemical composition of the diet used in partnership broiler farming system. The parameters observed included: the moisture, ash, protein, fat and fiber. The data obtained were tabulated and discussed descriptively. Based on the survey results, there are 8 partnership companies, namely PT. MSJ, PT. BBB, PT. Samsung, PT. DMC, PT. BSS, PT. FMS, PT. KUS and PT. PAL, and 6 types of feed used, namely S12, GM-PS, GM 1 EJ, Malindo, Wonokoyo, HD BR1 161. Average feed consumption is 3.24 kg / head / period, with weight gain of 2.10 kg / head / period, with the FCR value of 1.54. Based on the results of the evaluation of the nutritional content, there is a mismatch, especially the protein content which is lower (0.01%) as shown in the leaflet of the starter feed from Wonokoyo company. The conclusion of this study is that in general, the complete feed quality used is in accordance with the SNI based feed quality standards and the broiler productivity produced on partner farms meets the company standards.

Optimal Incentives

Hiring decisions are typically made by committees members of which have different capacity to estimate the quality of candidates. Organizational structure and voting rules in the committees determine the incentives and strategies of applicants; thus, construction of a modern university requires a political structure that provides committee members and applicants with optimal incentives. The existing political-economic model of informative voting typically lacks any degree of variance in the organizational structure, while political-economic models of organization typically assume a parsimonious information structure. In this paper, we propose a simple framework to analyze trade-offs in optimal subdivision of universities into departments and subdepartments, and allocation of political power.

Participatory on-farm evaluation of improved forage crops was conducted in six mixed farming system districts of Southern Ethiopia with the objective to identify farmers preferred forage crops (legumes and grasses). Two annual forage legumes (Vigna unguiculata L. (cow pea) and Lablab purpureus (L.), two perennial legumes (Medicago sativa (L.) (alfalfa) and Desmodium intortum (Mill.) Urb. (green-leaf)), and three perennial grasses (Chloris gayana Knuth (Rhodes grass) and two Pennisetum purpureum Schumach (elephant grass) accessions (No.16800 and 16798)) were evaluated in the study. The major farmers’ criteria considered in the evaluation of forage species were vegetative growth, herbage yield, tillering, protection of soil erosion, palatability, perfor- mance under dry weather conditions, performance in marginal area under low input management, multipurpose use (conservation and soil fertility) and fast growing condition. The study showed that elephant grass accession No. 16798, 16800 and Chloris gayana adapted well and farmers preferred them for their higher herbage yield, vegetative growth, tillering ability and drought resistance. Even though the annual forage legumes Lablab purpureus and Vigna unguiculata were superior in their forage yield, the farmers preferred the perennial forage legumes (Desmodium intortum and Medicago sativa) mainly for their performance under dry weather condi- tion due to their longer growth period. Therefore, the consideration of farmers’ preference for forage crops is crucial for increased adoption of improved forage crops in the region.
