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.

Ratoon Sugarcane

Groundwater and soil potassium deficiencies are present in northern India. Sugarcane is a vital crop in the Indian Punjab; it is grown on approximately 91,000 hectares with an average yield of 80 tonnes ha−1 and a sugar recovery rate of 9.59%. The role of potassium (K) fertilizer under both sufficient and deficient irrigation in ratoon sugarcane crops is not well documented. We conducted a split-plot ratoon cane experiment during 2020–2021 at the Gurdaspur Regional Research Station of Punjab Agricultural University, India, on K-deficient soils. Main treatments were fully irrigated (I1) and water stressed (I0) conditions, with sub-treatments reflecting K fertilizer application rates of 0 (M1), 67 (M2), 133 (M3), and 200 (M4) kg K ha−1. The ratoon sugarcane performance was assessed in terms of growth, productivity, sugar quality and incidence of key insect pests. At harvest, trends in the growth and yield parameters in I1 were improved over the I0 treatment, with cane height (+12.2%), diameter (+3.3%), number of internodes (+5.4%), biomass yield (+7.6%) and cane yield (+5.9%) all higher, although little significant difference was observed between treatments. Ratoon cane yield under irrigation was 57.1 tonnes ha−1; in water-stressed conditions, it was 54.7 tonnes ha−1. In terms of sugarcane quality parameters, measured 12 months after harvesting the initial seed crop, values of Brix (+3.6%), pol (+3.9%), commercial cane sugar percentage (+4.0%) and extractable sugar percentage (+2.8%) were all higher in the irrigated treatments than the water-stressed plot. Irrigated treatments also had a significantly lower incidence of two key insect pests: top borer (Scirpophaga excerptalis) was reduced by 18.5% and stalk borer (Chilo auricilius) by 21.7%. The M3 and M4 treatments resulted in the highest cane yield and lowest incidence of insect pests compared to other K-fertilizer treatments. Economic return on K-fertilizer application increased with increasing fertilizer dosage. Under the potassium-deficient water-stressed conditions of the region of north India, a fertilizer application rate of 133 kg K ha−1 is recommended to improve ratoon sugarcane growth, yield, and quality parameters and economic returns for sugarcane farmers.

Summary. Sub-zero temperatures can result in freezing injury of broccoli (Brassica oleracea L. var. italica Plenck) plants and thereby reduce head yield and quality. In order to predict effects of frosts, it is desirable to know the stages of development at which broccoli plants are most susceptible to freezing injury. In this study, the effect of a range of sub-zero temperatures for a short period at different stages of crop development were assessed and quantified in terms of mortality, yield and quality of broccoli. Whole plants in pots or in the field were subjected to sub-zero temperature regimes from –1 to –19°C. Extracellular ice formation was achieved by reducing temperatures slowly, at –2°C per hour. The floral initiation stage was most sensitive to freezing injury, as yields (fresh and dry head weights) were significantly reduced at –1 and –3°C, and the shoot apices were killed at –5°C. There was no significant yield reduction when the inflorescence buttoning stage was treated at –1 and –3°C. Although shoot apices survived the –5°C treatment at buttoning, very poor quality heads of uneven bud size were produced as a result of arrested development. The lethal temperature for pot-grown broccoli was between –3 and –5°C, whereas the lethal temperature for field-grown broccoli was between –7 and –9°C. The difference was presumably due to variation in cold acclimation. Freezing injury can reduce broccoli head yield and quality and retard plant growth. With regard to yield and maturity prediction, crop development models based only on simple thermal time without restrictions will not apply if broccoli crops are frost damaged.

To increase the area, production and productivity of sugarcane and legumes/oilseeds for increasing the profit of the farmers’, field experiments were conducted at Chaudhary Charan Singh Haryana Agricultural University, Regional Research Station, Karnal during 2005-06 and 2006-07 followed by demonstrations on intercropping of legumes/oilseed with sugarcane at farmers’ field in Kaithal district during 2009-10 and 2010-11. Cane yield did not reduce significantly due to intercropping except raya during 2005-06. The percent incidence of pink borer, shoot borer, top borer and root borer remained below economical threshold level (ETL). In all intercropping systems, total land equivalent ratio (LERt) was greater than unity, indicated yield advantage for the intercropped plots. Land equivalent coefficient (LEC) followed the same pattern as LERt. Total area time equivalent ratio (ATERt) values showed an advantage (22-28 %) with all intercropping systems than sole cropping with maximum advantage from sugarcane + chickpea. Sugarcane was more competitive than pea and lentil intercrops, whereas, raya and chickpea were more competitive than sugarcane. Higher competitive ratio values for the intercrops (CRi) indicated that all the intercrops were more competitive than sugarcane. Total values of actual yield loss (AYL) showed an advantage of 22-38% from intercropping compared to sole cropping. Highest monetary advantage index (MAI) value was obtained from sugarcane + pea intercropping system (75779). However, the minimum MAI was obtained from sugarcane + lentil intercropping system (62382). Demonstrations on intercropping at farmers’ field also resulted in higher gross returns, returns over variable cost and benefit: cost ratio.

SUMMARYBy comparing flowered and non-flowered plants of the same age (where flowering was inhibited by photoperiod control), cane yield gains due to prevention of flowering were estimated to be 56·6% in a plant crop and 33·8% in a ratoon crop. Sugar gain due to prevention of flowering was 69·1% in the plant and 35·4% in the ratoon crop. A simple negative linear relation was found between cane (and sugar) yield per plant and the proportion of canes that flowered. There was no significant difference in fibre content of flowered and non-flowered canes. The influence of loss of growth, side-shoot production and pithiness on the yield of flowered canes are discussed.

The foliar application of nutrients help the plant leaves to readily absorb the applied nutrients through the nutrient solution and increases the nutrient use efficiency and thus improves the crop yield. The field experiment was conducted for two consecutive years to find out the affect of foliar spray of NPK and micronutrient on cane yield, yield parameters and juice quality of sugarcane during 2019-20 and 2020-21.The present study was carried out on clay loam soils of Research farm of Regional Research Station, CCS Haryana Agricultural University, Karnal, Haryana. The research revealed that cane yield and yield parameters i.e., cane length, and cane weight was significantly affected with the foliar spray of NPK and micronutrient but non-significant effect was observed for cane girth and number of internodes. With respect to juice quality parameters viz., commercial cane sugar (CCS) %, pol % and sugar yield, significantly affected with foliar spray of NPK and micronutrient. The highest cane yield, cane weight and cane length was recorded with the foliar application of 2% NPK (19:19:19) + 0.5% ZnSO4 +1% FeSO4 (78.16 t/ha, 1.21 kg and 207.3 cm) followed by foliar spray of 0.5% ZnSO4 + 1% FeSO4+ 2.5% urea recorded 76.75 t/ha, 1.20 kg and 207.1 cm, respectively. The lowest cane yield (70.68 t/ha) was recorded with the application of recommended dose of fertilizer (RDF) alone. The highest CCS % (12.16), pol % (17.36) and sugar yield (9.51 t/ha) was observed in the treatment 2% NPK + 0.5% ZnSO4 +1% FeSO4. Thus, foliar application with NPK and micronutrient could significantly improve the cane yield, yield parameters and juice quality of sugarcane crop.

Cocoon silk, a high priced fabric, should be produced in large quantities to meet local and international demands using sustainable farming practices. To determine the effects of planting systems and agroecosystems manipulations on the mulberry growth, leaf yield, and quality for silk worm rearing, six agroecosystems manipulations using pit planting, organic manuring, inorganic fertilization, green and green leaf manuring were evaluated and the best alternative to increase production was selected. Pit planting method and fertilized with any of the following: (1) 100-5050 kg NPK/ha + 10 tons manure + green manure + mulch (LEISAI); (2) 5050-50 kg NPK/ha + 10 tons manures + green + green leaf manure + mulch (LEISA II); and (3) 10 tons manure + green manure + green leaf manure + mulch (Organic Farming I) gave higher mulberry leaf yields (taller mulberry plants, longer shoots, heavier single leaf weights), higher protein contents, and acceptable range of moisture (high moisture contents for young-age worms and low moisture contents for late-age silkworms). The use of sustainable and organic farming techniques can be a good alternative to conventional farming to improve the productivity of sericulture farms.

Eleven early maturing sugarcane clones were planted in Randomized Block Design for this study. The objective of this study was to investigate the relationships among the yield and quality parameters with cane yield and sugar yield in sugarcane, in order to provide information to help breeders in adopting traits for developing high yield and quality varieties. The analysis of variance revealed significant differences among genotypes for eleven yield and quality characters. Highest cane yield (176.66 t/ha) was recorded in clone 2015R10 and highest Commercial Cane Sugar (CCS) % (14.16) were observed in Co C 671. Correlation coefficient results indicated that cane yield was positively correlated with germination (0.166), number of millable canes (0.210), cane length (0.650), cane girth (0.610), single cane weight (0.880), CCS yield (0.518) whereas Brix% (-0.838), Sucrose% (-0.821), Purity % (-0.720) and CCS % (-0.812) showed negative correlation with cane yield. Sugar yield per hectare is positively correlated with purity% (0.187), cane length (0.413), cane girth (0.503), single cane weight (0.515) and cane yield (0.518). Results indicate that the genotypes should be selected on the basis of cane length, cane girth and single cane weight for getting higher sugarcane yield.
