Background: Under current scenario of High cost of Production of Sugarcane crop, it is need of time to decide specific seed rate for individual varieties. Sugarcane seed contributes to 10-20% of cost of production and farmers invests about Rs. 20000/- per acre on planting material. The costs of seed can be curtailed by optimizing seed rate. Similarly, seed rate varies with different varieties. In this view, a field experiment was carried out to optimize the seed rate of promising sugarcane clones.Methods: A field experiment was carried using randomized complete block design with factorial arrangements having three replications at Sugarcane Research Institute, Faisalabad during 2016-17 and 2017-18. Result: The results revealed that maximum cane diameter was recorded for S2008-AUS-133 at seed rate of 25000 and 50000 triple budded setts/ha. However; maximum number of canes/ha were recorded for S2008-AUS-133 at seed rate of 75000 setts/ha followed by HSF-240 at 75000 setts/ha. Maximum cane yield was noted for HSF-240 at seed rate of 75000 followed by S2008-AUS-133 at seed rate of 50000 and lowest can yield was recorded in S2003-US-127 at seed rate of 25000 triple budded setts/ha. Genotypic and phenotypic variances were higher for plant height (381.63, 133.91 cm) and cane yield (406.50, 330.65 kg/plot).Genotypic and phenotypic coefficient of variances were moderate for number of tillers (11.6%, 15.44%) and higher for cane yield (20.24%, 22.44%). It means that variability in 4 genotypes for cane yield was higher. Thus variety S2008-AUS-133 showed better performance at seed rate 75000 while during selection, number of tillers and height should be considered for further breeding program.

Abstract The effect of chemicals (Reglone 200 SL and Elastiq 550 EC) on soil microorganisms and their enzymatic activity was estimated. The study was conducted in a field experiment which was set up in the split-block design and comprised three treatments. Soil samples were taken six times, twice in each year of study. The results showed that the application of chemicals generally had no negative effect on the number of soil microorganisms. The application of Reglone 200 SL caused an increase of proteolytic and ureolytic activity and affected the activity of dehydrogenases, acid and alkaline phosphatases in the soil. The soil subjected of Elastiq 550 EC was characterized by lower activity of dehydrogenases, protease, urease and alkaline phosphatase.

Remote sensing techniques and the use of Unmanned Aerial Systems (UAS) have simplified the estimation of yield and plant health in many crops. Family selection in sugarcane breeding programs relies on weighed plots at harvest, which is a labor-intensive process. In this study, we utilized UAS-based remote sensing imagery of plant-cane and first ratoon crops to estimate family yields for a second ratoon crop. Multiple families from the commercial breeding program were planted in a randomized complete block design by family. Standard red, green, and blue imagery was acquired with a commercially available UAS equipped with a Red–Green–Blue (RGB) camera. Color indices using the CIELab color space model were estimated from the imagery for each plot. The cane was mechanically harvested with a sugarcane combine harvester and plot weights were obtained (kg) with a field wagon equipped with load cells. Stepwise regression, correlations, and variance inflation factors were used to identify the best multiple linear regression model to estimate the second ratoon cane yield (kg). A multiple regression model, which included family, and five different color indices produced a significant R2 of 0.88. This indicates that it is possible to make family selection predictions of cane weight without collecting plot weights. The adoption of this technology has the potential to decrease labor requirements and increase breeding efficiency.

Weeds Control

Background: Weeds are one of major threats to crop yield and quality. Weeds compete with cane crop and reduce the yield significantly in a very short period. Planned use of all available farm resources leads to integrated control strategy. The current study aimed to study the use of inter row rotary weeder for integrated weeds management to control population dynamics of weeds in sugarcane crop. The objective of experiment is to find out economical, feasible and easy to use approach to minimize the weed density below the threshold level in sugarcane crop and to minimize the use of chemicals for weeds control to promote organic farming. Method: In this research experiment, at Sugarcane Research Institute, Faisalabad during 2017 and 2018, the treatment includes viz. Application od Click (atrazine and acetochlor) @ 3.75 Liter per hectare as Pre-emergence, Ametryn + Atrazine 80 W.P @ 2.50 kg per hectare as post-emergence, Machanical Inter-culture with Rotary weeder and cultivator plough and earthing up. These treatments in different combinations were compared with control. Results: The application of Pre-emergence weedicide Click (atrazine and acetochlor) @ 3.75 Liter per hectare + Inter culture with Rotary weeder 50 days after planting (DAP) + Inter culture with cultivator plough before earthing up (100 DAP) produced significantly higher cane yield of 105 t. ha-1 and highest net benefits per hectare of Rs. 156250/-. The lowest cane yield of 70 t. ha-1 was noted from the experimental units with Weedy check / control. If farmers use this approach, the use of post emergence weedicides will be minimized and will encourage organic farming with safe and healthy environment.

Haricot bean (Phaseolus vulgaris L.) is an important cash crop and protein source for farmers in many parts of Ethiopia. However, its production is limited by phosphorus fertilizer. Therefore, field experiment was conducted at the Malle woreda in Koybe kebele farmers training center during the main rain season of 2016 to investigate the responses of haricot bean to different levels of phosphorus fertilizer and its effect on growth, and bean yield. Four phosphorus rates (0, 23, 46, and 69kg ha-1) were used as treatments were laid out in a randomized complete block design with three replications. Red Wolaita haricot bean variety was used as planting material. Recommended rate of N (46 kg/ha) was applied to all treatments. The effect of phosphorus was significantly (P less than 0.05) increased bean yield and growth parameters such as leaf area and number of branches per plant, whereas its effect was not significant on plant height. Based on result obtained, application of 46kg P ha-1 is recommended for better production of haricot bean at Malle woreda and similar areas which have the same soil property.

A field experiment is conducted to study the effect of different levels of peat (0, 25, 50, 75, and 100 Mg ha-1 to uncropped and cropped soil to wheat. Soil samples are taken in different period of time (0, 3, 30, 60, 90, 120, and 180 days after cultivation to determine (NaHCO3-Exteractable P at 3 different depths (0-10, 10-20, and 20-30 cm). Field Experiment is conducted in a randomized complete block design (RCBD) with four replicates. Wheat, Al-Rasheed variety, is cultivated as a testing crop. The entire field is equally dived in two divisions. One of the two divisions is cultivated to wheat and the second is left uncropped. The effect of five levels of peat namely 0, 25, 50, 75, 100 Mg ha-1 is investigated. Soils are fully analyzed to determine its physical and chemical characteristics. The soil samples are collected after 3, 30, 60, 90, 120, and 180 days for determining essential parameters and indicators that reflect the effect of the level of peat applications. Sodium bicarbonate - extractable P in uncropped and cropped soils at all depths, markedly decreases with time after peat application which has been attributed to plant uptake and rapid reaction of P with soil constituents. Sodium bicarbonate - extractable P with time in soil receiving 50 Mg ha-1 in both uncropped and cropped soil linearly decreases with the time of cultivation

Weed Control Efficiency

Background: Time of pre-emergence herbicide application is an important factor that decides the efficiency of herbicide. If the pre-emergence herbicide is not applied at appropriate time, it may cause ineffective weed control or toxicity to crops. With this background, a field experiment was conducted at TNAU, Madurai to optimize the time of pre-emergence herbicides namely pendimethalin and oxyfluorfen application for effective weed management in irrigated blackgram. Methods: The experiment was laid out in randomized block design with three replication. Treatments were application of pendimethalin at 0.75 kg ha-1 and oxyfluorfen at 0.2 kg ha-1 on 1, 2, 3, 4 days after sowing, weed free check and unweeded check. Result: Results of the study revealed that oxyfluorfen gave maximum weed control efficiency as compared to pendimethalin, but toxicity to the crop was observed when oxyfluorfen was sprayed after 2 days of sowing. Yield and economics were achieved higher with application of 0.75 kg ha-1 of pendimethalin at 2 DAS, which was on par with application of 0.2 kg ha-1 of oxyfluorfen at 1 DAS due to lesser toxicity. Application of 0.75 kg ha-1 of pendimethalin and 0.2 kg ha-1 of oxyfluorfen didn’t leave any herbicide residue after harvest. Hence, application of 0.75 kg ha-1 of pendimethalin at 2 DAS and 0.2 kg ha-1 of oxyfluorfen at 1 DAS can be recommended for effective weed management in irrigated balckgram.
