THE IMPACT OF CURRENT COTTON PRICE AND PRODUCTION COSTS ON SKIP-ROW COTTON

According to conventional wisdom, low prices favor skip-row planting patterns while high prices favor solid planted cotton. Production costs have been trending upward for many years. Current high production costs have redefined the point at which a low price becomes a high price relative to skip-row versus solid planting pattern decisions. Growers considering a shift from solid to skip-row cotton must be able to produce high yields, more than 90% of the solid yield on a land acre basis.cotton, no-till yields, returns, Production Economics,

The effect of vegetation patterns on Aeolian mass flux at regional scale: a wind tunnel study

Although insight on the effect of vegetation pattern on Aeolian mass transport is essential for re-planting degraded land, only limited knowledge on this effect is available. The objective of this research was to understand the effect of vegetation design on the Aeolian mass flux inside a single land unit and at the borders among land units. A simulation of Atriplex halimus shrubs inside a wind tunnel was made, and sand redistribution was measured after the application of 200-230 seconds wind at a speed of 11 ms-1. The study showed that: 1) sediment maximum transport inside a single land unit is related to the neighboring land units and to the vegetation pattern within both the unit itself and the neighboring land units; 2) the effect of neighboring land units includes the protection effect and the ruling of sediment crossing from one land unit to the neighboring land units; 3) for the designing of re-planting of degraded land the ‘streets’ (zones of erosion areas similar to streets) effect need to be considered; and 4) in addition to the general knowledge needed on the effect of vegetation pattern on the erosion and deposition within an area, it is important to have insight on the redistribution of sediment at small scales upon the aim of the project

Evaluating system of rice intensification using a modified transplanter: A smart farming solution toward sustainability of paddy fields in Malaysia

This paper presents the study reports on evaluating a new transplanting operation by taking into accounts the interactions between soil, plant, and machine in line with the System of Rice Intensification (SRI) practices. The objective was to modify planting claw (kuku-kambing) of a paddy transplanter in compliance with SRI guidelines to determine the best planting spacing (S), seed rate (G) and planting pattern that results in a maximum number of seedling, tillers per hill, and yield. Two separate experiments were carried out in two different paddy fields, one to determine the best planting spacing (S=4 levels: s1=0.16 m×0.3 m, s2= 0.18 m×0.3 m, s3=0.21 m×0.3 m, and s4=0.24 m×0.3 m) for a specific planting pattern (row mat or scattered planting pattern), and the other to determine the best combination of spacing with seed rate treatments (G=2 levels: g1=75 g/tray, and g2= 240 g/tray). Main SRI management practices such as soil characteristics of the sites, planting depth, missing hill, hill population, the number of seedling per hill, and yield components were evaluated. Results of two-way analysis of variance with three replications showed that spacing, planting pattern and seed rate affected the number of one-seedling in all experiment. It was also observed that the increase in spacing resulted in more tillers and more panicle per plant, however hill population and sterility ratio increased with the decrease in spacing. While the maximum number of panicles were resulted from scattered planting at s4=0.24 m×0.3 m spacing with the seed rate of g1=75 g/tray, the maximum number of one seedling were observed at s4=0.16 m×0.3 m. The highest and lowest yields were obtained from 75 g seeds per tray scattered and 70 g seeds per tray scattered treatment respectively. For all treatments, the result clearly indicates an increase in yield with an increase in spacing.DFG, 414044773, Open Access Publizieren 2019 - 2020 / Technische Universität Berli

Development of a mechanization selection system for oil palm plantations with alternative planting patterns

This article describes a study on the conceptual design and development of the most efficient mechanization selection system for oil palm plantations with alternative planting patterns. The study was conducted by extrapolating various planting patterns based on the existing triangular pattern and comparing these with machine information based on a constant mechanization package made for a large and rather flat area. The comparison of machines was conducted in earlier studies based on a combination of various plantation operations like fertilizer application, weeding, harvesting, in-field collection and loose fruit collection. The results obtained suggest that the most efficient planting pattern is the triangular planting pattern. The findings from this study will help to determine the efficiency of each machine besides optimizing the cost of implementing the package

Kajian Defoliasi Sorgum Pada Tumpangsari Dengan Kacang Hijau*)

Study on Defoliation of Sorghum under Cropping Pattern by Mungbean. The aim of the research was to find out the effect of defoliation of sorghum under cropping pattern toward the yield of sorghum, Mungbean and total relative result of the best sorghum and Mungbean in intercropping system has been carried out in Kebun Percobaan Fakultas Pertanian Universitas Gadjah Mada in Banguntapan, Bantul Regency from February up to June 2006. The research method used was split plot design with 2 factors and 3 repetitions. The main factor was defoliation of sorghum comprising of 2 levels: sorghum defoliation (D1) and without sorghum defoliation (D2). The sub factor of sub was cropping pattern, comprising of 5 levels: monoculture of Mungbean (H100). 75% sorghum: 25% Mungbean (S75 H25), 50% sorghum: 50% Mungbean (S50 H50), 25% sorghum: 75% Mungbean (S25 H75) and monoculture sorghum (S100). The results of the study showed that 1) the defoliation sorghum did not affect the yield of mungbean and sorghum, 2) cropping pattern of mungbean monoculture resulted bean/plant amount, seed/plant weight and seed weight/ha of mungbean as higher compared to other cropping pattern, 3) cropping pattern of 25% sorghum: 75% mungbean resulted seed weight/malai sorghum was higher compared to other planting patterns and the highest seed weight/ hectare was resulted in sorghum monoculture planting pattern, 4) the highest total relative yield was 1,303 given planting pattern at 50% sorghum: 50% mungbean and 5) the form of the relation between sorghum and mungbean in intercropping pattern and sorghum defoliation was complementary, while intercropping and without sorghum defoliation was supplementary

The Air Flow Analysis of Coffee Plantation Based on Crops Planting Pattern of the Triangular Grid and Shackle of Wheel graphs by using a Finite Volume Method

Coffee bean is one of the Indonesia major export commodity. Based on the data from the 2012, Indonesia was ranked at third biggest coffee beans exporter in the world, after Vietnam and Brazil. A coffee land expansion have been done to increase the productivity of coffee beans, however it is not so effective. One of the factors that affect the productivity is a crops planting pattern. A good crops planting pattern will make a good air circulation and it will finally affect to the productivity of coffee beans. We will use a finite volume method to analyze the air flow of coffee plantation based on the soil roughness level, crops planting pattern of the triangular grid and shackle of wheel graphs. The simulation process is carried out by using MATLAB and FLUENT softwares. The result shows that the crops planting pattern of triangular grid and shackle of wheel graphs gives a better air circulation process in the coffee bean plantation

Keselarasan Penyediaan Nitrogen dari Pupuk Hijau dan Urea dengan Pertumbuhan Jagung pada Inceptisol Darmaga

Increasing N use efficiency and decreasing N pollution can be achieved by synchronization between supplying pattern of N and crop N demand. Leaching-incubation experiment had been carried out for evaluating supplying pattern of N from 14 treatments of green manure (Flemingia and Gliricidia), urea and their combinations. Only 5 treatments of the split application of Gliricidia, urea and their combinations, and single application of combination of urea and Gliricidia synchronize with corn N uptake model. These five fertilization treatments were further examined in the greenhouse and in the field experiment. The synchronization between supplying pattern of N and corn growth in treatment without leaching was resulted by application of urea at planting followed by Gliricidia at 3 weeks after planting (WAP) and urea at planting and 3 WAP, whereas in treatment with leaching were resulted by split application of Gliricidia at planting and 3 WAP, urea at planting followed by Gliricidia at 3 WAP, and single application of urea and Gliricidia at planting. Urea applied at planting followed by Gliricidia at 3 WAP resulted in the high production of seed dry-weigh with low N inorganic leaching
