Irrigation Levels

The increasing scarcity and competition for irrigation water entails adoption of innovative practices that increase efficient water use. The objective of this research was to compare different mulching techniques and investigated the combined effect of irrigation levels under drip irrigation system based on the parametric evaluation system in western part of Ethiopia during the 2018 dry season. A factorial combination of five levels of water (namely 100%, 80% and 70%, 60% and 50%ETc) combined with three mulch treatments (namely, Normal Mulch (NM), Straw Mulch (SM) and Plastic Mulch (PM)) with three replications. The analysis of variance showed that, days to 50% maturity, leaf number per plant, mean leaf length, plant height and leaf area were significantly affected by the main effects of deficit irrigation levels and mulching materials. The interaction effects of deficit irrigation levels and mulching materials significantly influenced plant height, number of leaf per plant, plant height, Leaf length and Leaf area of the onion. The present study suggests that, in water scarce area, farmers are advised to adopt deficit irrigation level with 80% ETc under plastic mulch. It is important even to undertake similar studies at different seasons with different varieties in consideration of their cost benefit analysis. However, if water is not a limiting factor, farmers are advised to apply full irrigation water application under plastic mulch.

Utilization of the potential of marginal land with adequate water and nutrients is an important factor in increasing corn production. However, high porosity levels and low nutrient levels cause growth and production of corn is not optimal. The aim of this research is to obtain an irrigation technique combined with efficient fertilization in the sweet corn cultivation system in marginal land. The field research was carried out at Faculty of Agricultural Research Wedomartani, Depok Sleman Yogyakarta. The study was conducted from September 2019 to February 2020. The research aims to get best sweet corn line at various concentrations of liquid organic fertilizer in marginal land with a drip irrigation system.The research was arranged in a completely randomized design (CRD) with 3 replications. The first factor is sweet corn lines, which consists of 9 levels, namely, G1 (5042B), G2 (KD-11), G3 (KD-13), G4 (SB-11), G5 (SB-13), G6 (SB-14), G7 (SB-16), G8 (SB-21), and G9 (SB-22). While the second factor is the irrigation system combined with fertilization (fertigation) which consists of 3 levels, namely the drip irrigation system with a concentration of liquid supplement fertilizer 2 cc / L, 3 cc / L and 4 cc / L. The results showed that the drip fertigation system with a concentration of POC 3 cc / L was able to give a better effect on plant height and leaf length in sweet corn. SB / 1-3 lines was the best lines as prospective parents for making hybrid lines for plant height, leaf length, number of leaves and cob length.Keywords: lines, liquid organic fertilizer, sweet corn, marginal land, irrigation system

The effect of plastic mulch on chickpea (Cicer arietinum L.) cultivation under low head drip irrigation systems was studied at ICAR-Central Institute of Agricultural Engineering, PFDC, Bhopal during 2018-19. Drip irrigation system was operated by placing water tank at a total water deliver height of 3 m and varied heads to 2.5 m and 2.0 m to find out the value of coefficient of uniformity under these heads. The experimental treatments consisted in five levels by varying irrigation methods: Flood irrigation, irrigation with drip laid on raised beds, irrigation with drip laid on raised beds covered with black mulch, irrigation with drip laid on raised beds covered with silver mulch and irrigation with drip laid on raised beds covered with white mulch. Growth and yield parameters of chickpea viz., plant height (cm), number of branches per plant, plant dry matter (g/plant), effective nodule per plant and nodules dry weight (mg/plant), number of pods per plant, 100 seed weight, seed yield (kg/ha) and harvest index were highest under silver plastic mulch laid on raised beds, irrigated with drip as compared to black plastic mulch and white plastic mulch treatments. Lowest growth and yield parameters were recorded in the flood irrigated treatment. Water Use Efficiency was highest under silver plastic mulch (17.21kg/ha mm) and lowest under flood irrigated condition (3.74 kg/ha mm). Net returns were higher in the treatment under the silver mulch (Rs/ha 77939) and followed by black mulch (Rs/ha 67179) with lowest net returns in the flood irrigated condition (Rs/ha 32690).

AbstractA study was conducted to design productive, profitable, irrigation water¸ nitrogen and energy use efficient intensive cereal systems (rice-wheat; RW and maize-wheat; MW) in North-West India. Bundling of conservation agriculture (CA) with sub-surface drip irrigation termed as CA+ were compared with CA alone and conventional tillage based and flood irrigated RW rotation (farmer’s practice; ScI). In contrast to conventional till RW rotation which consumed 1889 mm ha−1 irrigation water (2-yr mean), CA+ system saved 58.4 and 95.5% irrigation water in RW and MW rotations, respectively. CA+ practices saved 45.8 and 22.7% of irrigation water in rice and maize, respectively compared to CA with flood irrigation. On a system basis, CA+ practices saved 46.7 and 44.7% irrigation water under RW (ScV) and MW (ScVI) systems compared to their respective CA-based systems with flood irrigation (ScIII and ScIV). CA+ in RW system recorded 11.2% higher crop productivity and improved irrigation water productivity by 145% and profitability by 29.2% compared to farmers’ practice. Substitution of rice with maize (MW system; ScVI) recorded 19.7% higher productivity, saved 84.5% of irrigation water and increased net returns by 48.9% compared to farmer’s practice. CA+ RW and MW system improved energy productivity by 75 and 169% and partial factor productivity of N by 44.6 and 49.6%, respectively compared to ScI. The sub-surface drip irrigation system saved the fertilizer N by 20% under CA systems. CA+ in RW and MW systems recorded ~13 and 5% (2-yr mean) higher profitability with 80% subsidy on installing sub-surface drip irrigation system and similar profitability without subsidy scenario compared with their respective flood irrigated CA-based systems.
