This study was conducted in order to determine effect of water requirement, irrigation treatments and water use efficiency of capsicum crop. Experiments were carried out in the College of Agricultural Engineering, Madakasira between January to May 2018, with cv. Indra. The maximum yield of 4.3 t ha -1 was obtained from treatment 1(1.0 ET c ). The seasonal irrigation water amount of treatment was 562.5 mm determined by AquaCrop 6.0 model. Capsicum yield of 3.8 t ha -1 was obtained under treatment 2 (0.75 ET C ) of 421.87 mm seasonal irrigation water requirement and under treatment 3 (0.5 ET C ) 2.1 t ha -1 with the seasonal irrigation water amount of 281.25 mm. Although water saving of 140.63 mm in treatment 2 and 281.25 mm in treatment 3. The method of determination of water requirement is AquaCrop 6.0 model. Predicted water requirement through AquaCrop is compared with the pan evaporation data. From this experiment AquaCrop model appeared to be most reasonable and effective one in terms of yield and WUE. On the other hand, the maximum irrigation water use efficiency 9.19 kg ha -1 mm -1 in treatment 2 followed by treatment 1 and treatment 3.

The influence of different deficit irrigations on capsicum crop biometric parameters and fruit yield were assessed in an experiment the variety ‘Indra’ was tested using completely randomized block design with three deficit irrigations (0.50, 0.75 and 1.0 ETC) and 5 replications in polyhouse and 1.0 ETC in open field conditions. The biometric parameters namely plant height, number of leaves, number of branches, number of days to flowering; number of days to harvesting, number of fruits per plant, individual fruit weight and fruit yield are measured. From the results, observed that, average of plant height (91.23 cm), number of leaves (91.3), number of branches (6.9), number of days to flowering (32.7), number of days to harvest (71), fruit number per plant (7), individual fruit weight (75.99 g) and yield (6466.66 t ha-1) parameters found higher in 1.0 ETC (T1), but in case of water productivity (12.4 kg ha-1 mm-1) in the treatment (T2) 0.75 ETC showed superiority. From the results, it is determined that by adopting the 0.75 ETC (T2) we can save the water up to 25%. Aims: The objective of this study is to evaluate the influence of deficit irrigation in biometric parameters of capsicum. Study Design:  Completely randomized block design. Place and Duration of Study: Experiment conducted during January to May 2018 at Agriculture farm, College of Agricultural Engineering, Madakasira located in Rayalaseema region. Methodology: Physical and chemical properties of field were found by using standard methods. The experiment was arranged using CRD design with three levels of irrigation and five replications. Fertigation was done with 250:150:150 kg/ha recommended doses of N:P:K to capsicum crop. Based on climatological approach (evapotranspiration basis) the quantity of water applied. All the recommended cultural practices selection of cultivars, nursery raising, land preparation, laying drip lines, fumigation, fertilizer application, transplanting, pruning, training and plant protection measures are removing affected plant parts, flowers, fruits and for thrips and aphids management are dicofol (2 ml/L) and imidacloprid (0.5 ml/l) standardized for polyhouse were followed time to time to ensure a healthy crop stand. Crop water requirement was determined by using AquaCrop model. The parameters viz., plant height, number of leaves per plant and number of branches per plant were recorded at 30, 60, 90, 120 days after transplanting and at harvest. The collected data of different parameters during the course of research were analysed as per the completely randomized design (CRD) by applying the technique of analysis of variance procedure. Results: Among all the treatments, Irrigation with 100% Crop Evapotranspiration (1.0 ETc) (T1) registered the highest plant height, number of leaves, number of branches, number of days required to harvesting, number of days required to flowering, fruit number, average fruit weight and fruit yield, followed by 0.75 ETc (T2), 0.5 ETc (T3) and open field conditions. This might be due to good soil moisture distribution in drip irrigation compared to the open field. From the observed parameters it is exhibited that drip irrigation 0.75 ETC recorded as the higher water productivity (12.4 kg ha-1 mm-1) followed by drip irrigation scheduled at 1.0 ETC (11.49 kg ha-1 mm-1), 0.5 ETC (11.07 kg ha-1 mm-1) and open field (1.38 kg ha-1 mm-1) recorded very less. Conclusion: By adopting T2 (0.75 ETC) irrigation treatment we can save the water up to 25%, by using saved water additional quantity of vegetables can be produced.

:Rice is one of the most important cereals that hold the key for food security. SRI has reached certain level of acceptance among the research and scientific community in major rice producing countries. The SRI method of rice cultivation involves planting single seedling in wider row spacing i.e., 25x 25 cm, which involves more labour intensive and laborious process. Hence, the present study was conducted with an objective to compare the mechanized rice transplanting with different intra row spacing with mechanized rice transplanter method with SRI and normal method of rice cultivation. The study was conducted with four treatments i.e.

This study was conducted to investigate on alternative tray filling materials to replace the soil media on crop growth, yield characteristics and yield attributes in The Mechanized System of Rice Intensification (MSRI). Focusing on the different alternative filling materials suitable to replace the soil media with 100% seed germination, Ten treatments with different combinations were experimented and a fine thin layer of well decomposed farm yard manure was spread over all ten treatments o bed filling material [(i.e., T 1-10% groundnut shell + 90 % soil; T 2-10% vermin-compost+ 90% soil; T 3-10% rice husk+90% soil; T 4-25% vermin-compost + 75% soil; T 5-25% rice straw + 75% soil; T 6-25% rice husk + 75% soil; T 7-10% rice straw+ 90% soil; T 8-25% groundnut shell +75% soil; T 9-Field soil (100%) (MT); T 10-Manual plantin (MP)]. The observation of transplanted hills was also noted in root growth and leaf number, leaf area index and number of tillers and panicle number, panicle length and grain number per panicle, grain filling and 1000-grain weight and straw weight. The raising nursery with different bedding materials transplanted with machine significantly influenced grain yield per hectare. The results revealed that highest grain yield per hectare was observed with T 8 (25% GS) as 4858.5 kg/ha and followed by T 4 (25% VC) as 4685 kg/ha. However, the lowest grain yield was recorded at 2212.6 kg/ha was observed in T 6 (25% RH), due to lowest N, P, K contents in rice husk bed material. It is also observed from transplanted crop that root length was highest with T 5 (25% RS) as 11.39 cm followed by T 3 (10% RH) as 11.16 cm, whereas lowest root length 9.10 cm, root spreading was highest with T 8 (25% GS) as 20.72 cm followed by T 1 (10% GS) as 19.46 cm, T 2 (10%VC) as 19.00, T 4 and 9 are comparable with each other and is 18.47 cm. whereas lowest root spreading 13.08 cm was observed in T 10 (manual planting). Finally it has been concluded that there is significant effect of bedding materials on crop growth and yield parameters.
